Me-262 swept-wing vs Ho-229 flying-wing

The Me-262 was well-documented but the Ho-229 remains mysterious.
According to the Horten brothers, a simulated dogfight was conducted between the Ho-229 and Me-262.
The Ho-229 outperformed the Me-262 by a wide margin.
The Ho-229 had lower wing-loading and its (untested) design speed was 1000 KPH (600 MPH).

Me-262 vs Lockheed L-133 and P-80

Lockheed began designing its L-133 Starjet back in 1939.
Oddly, the early L-133 was more advanced than Lockheed's later P-80 Shooting Star which flew in 1944.

The L-133's airframe was never built. Its engine was, but it wasn't a success.
The design had canards. Wings, fuselage, and engines were blended.
Design speed was 600 MPH. But to reach this speed requires
keeping the wings outside sonic shock-waves, either with swept wings or a long nose.
The L-133 and Lockheed's later F-104 Starfighter have a long nose which allows straight wings.
Possibly Lockheed engineers first discovered or anticipated this, but kept it a secret (?).
Or the wings were at the rear simply because it was a canard design (?).
Was the nose long rather to provide space for fuel (?).

The Me-262 had different advanced features: swept wing and leading-edge slats.
It had drag/weight/maneuverability disadvantages with engines slung under its wings.
Its tail-plane had elevators, but the whole thing could be rotated (all-moving tail).
All-moving tails solve lack of control at transonic speeds, which the US didn't solve
until years later in the F-86 Sabre (a British engineer predicted and solved this prior).

The P-80 was a conventional straight-wing (and rather ugly) design with a jet engine shoved in.
Lockheed can't be blamed. It was what the USAF ordered, a conservative design, not a risky advanced one.
Two preproduction YP-80s were deployed very late in WWII but no action occurred.
After WWII, the US conducted simulated dogfights with the Me-262 vs P-80,
and concluded they were evenly matched, as their advantages/disadvantages cancelled out [ref: "Yeager"].

As for Me-262 vs L-133, the L-133 might not have been a viable design (?). Its inlet looks too small.

F-14 Tomcat vs F-18 Hornet

The F-14 was designed as a long-range interceptor and tight-turning dogfighter.
The F-18 was designed as cheaper airplane by compromising performance.

By design, the F-18 was inferior in almost every respect. It couldn't reach Mach 2, had a shorter range, wings optimal for a narrow speed range, etc. The F-18 had more modern avionics but avionics can be upgraded. In USAF competition with the F-16, the F-16 won, yet the F-16 aggressors were defeated by Navy F-14 students.

The F-18 replaced the F-14 mainly for political and business reasons. Idiot politicians [ref: Dick Cheney] assumed a plane with a greater numeric designation was superior. Grumman knew the Navy knew the F-14 was superior and bet the Navy would pay a high price for building new Tomcats. But the Navy went shopping. What the Navy got was a hack -- the "Super Hornet" is just a scaled-up Hornet.

F-14 Tomcat vs F-22 Raptor

Iran still flies their F-14 Tomcats (the US was foolish to sell them).
An F-22 intercepted an Iranian F-4 Phantom and the Raptor pilot aggressively flew alongside.
(The incident was absurd -- a $250 million human-piloted airplane was protecting an expendable drone.)

What would've happened if instead an F-14 was flying and the Iranian pilot was brave?

F-16 Viper vs F-18 Hornet

As a dogfighter, the F-16 is superior.
After the YF-16/YF-17 competition, the USAF said the F-16 was a better plane.
F-16 is lighter, less drag, faster, greater acceleration, higher G, faster roll, etc.
F-18 has one small advantage: it can whip its nose around at low speeds.

F-15 Eagle vs MiG-25 Foxbat

The US thought its F-15 Eagle would be more than a match for a Soviet MiG-25 Foxbat.
But Iraqi MiG-25s proved otherwise when they evaded missiles by dropping chaff/flares,
and evaded guns by simply outrunning F-15s.

They look similar. The MiG-25 was introduced first.
The basic shape of the MiG-25, F-14, F-15, and F-22 originated from North American's Vigilante (designed in ~1950).

F-15 Eagle vs F-22 Raptor

The F-15 has great speed and rate-of-climb,
but its maneuverability is sub-par compared to an F-14 and F-16.
F-15 airframes are worn and need to be replaced.
But the F-22 is terribly unreliable (despite 20 years of development).
Some advocate the semi-stealthy F-15 Silent Eagle as a lower-tech complement (like the B-52 complements the B-1).

F-22 Raptor vs Su-47 Berkut forward-swept wing

Pointless because the Su-47 won't ever be produced, but will do a comparison just for fun.

No doubt the Su-47 can outmaneuver the F-22.
The Su-47 has more lift area, it has two-axis thrust vectoring vs the F-22's one-axis,
and forward-swept wings are more maneuverable than backward-swept.
The Su-47 would win if it can get within visual range
(unless the F-22 avionics computer can automatically dodge bullets).
But the F-22 is designed to kill Russian fighters from a distance.
But so was the F-4 Phantom.

F-35 vs MiGs/Sukhois

If detected by a MiG/Sukhoi, and unless its avionics can't dodge missiles/bullets,
the over-weight F-35 with its tiny stubby wings will be shot from the sky with ease.

F-35 vs A-10 Wart Hog

The A-10 was specifically designed for the role of close-air support.
Stealth isn't really needed for this role. A big cannon is needed, A-10 has one, the F-35 doesn't.

X-29 vs Su-47

The X-29 was smaller and much lighter (25% of the Su-47's weight).
The Su-47 has two-axis thrust vectoring.
Both are three-surface designs which enhance maneuverability.
A dogfight would be too close to call.

SR-71 Blackbird vs MiG-31 Foxhound

(Supposedly) MiG-31 Foxhounds were able to "intercept" Blackbirds.
A carefully launched squadron of MiG-31s, for a short time,
were able to get underneath and within radar range,
threatening the Blackbird pilot with a possible long-range missile shot.
MiG-25 Foxbats weren't much of a threat because of its less-capable radar/missiles.
