I've actually played them all now:
P-51H I've recently re-purchased, enjoying the heck out of it, would be a keeper but I don't really like it visually.
XF5U I'm working on Specialising, so-far fairly meh, was a pretty rough stock grind starting with MGs & slow.
F2G like the P-51H I like the performance but not the grille on the top of the nose.
XP-72 I love the look of it & its fun tearing around at high speed with the firepower of F-86A. Not so fun when caught low-speed & out of boost.
La-9 my first T8, still love it even if its quite outclassed by many other T8s.
Su-9 I did not enjoy, its an uglified, sluggish & altitude restricted 262 with a derp.
Yak-15 I didn't think much of on the way through, dig the look though. Re-purchased & working on Specialising on strength of trouble caused to Vampire by Player Specialists. I think its going to be really powerful once Specialised.
I-250 was nothing special grinding through, could be interesting Specialised & geared up but not a pretty plane.
Il-20 powerful but ugly as sin.
Tu-10 is a Bomber in an era that Bombers are awful to play.
Me 209A I fairly enjoyed but played with the Mk 108, re-purchased & Specialised 109 G instead.
Ta 152 has a lot of potential if I could just get the guns to land reliably, working on Specialising.
BVP.210 Just started playing this weekend, its a ball of fun.
Me 262 has that high-altitude, high-speed absolute dominance feel, you're up high & fast, nobody else deserves to be up there with you
(carefully ground up other lines first so it got 2d best engine from stock)
Me 329 is quite an enjoyable GA, the quad 108s, quick loading bombs & effective tailgunner are nice.
Ju-288C see Tu10 but nobody can hear you scream up there.
Ki-94II only just started flying this weekend, a somewhat faster Ki-84 but in this tier that may not be enough to stay competitive.
J7W1 just finished the grind to W2, started out fun, ended up an unpleasant grind. Does hit hard & kinda cool looking.
Spitfire XIV sleek, decently quick, quad 20mm, Spitfire turning, arguably a bit samey.
Tempest oh glorious beautiful Tempest with your quad 20mm, good speed & solid 10s turn
(even though in practice somewhat outclassed vs the likes of Vampires)
P.1056 ugly as an ugly gecko thing, I expected very little, had an absolute ball playing it with its monstrous firepower 
Actually much less fun when I came back to Specialise it for some reason, probably mentally over-estimating its ability & putting it where it shouldn't be.
