I've built mostly Hasegawa kits so far, all in 1/32. So far they include:
Ju 87 G2 (huge wingspan, absolute monster)
Bf 109 G10
Bf 109 K4
Spitfire Mk V
Fw 190 D9
Fw 190 A5
Me 262 A1
Me 163 (very old Hasegawa kit, good none the less)
I've found them to be good for the intermediate modeller (as I am, I'm no expert), they're cheap and easy to build.
They're a bit lacking on detail here and there, though.
I'm building a Revell Bf 109 K4 at the moment and I've not noticed a great deal of difference between the kits so far (I'd not be surprised if the kits were made by the same people at this stage).
I haven't gone to the same lengths with detail as Pipz, magnificent job on that Spitfire mate, it looks beautiful.
