i dont have the chance to feels all manufaturer..but here's goes my opinion
AFV - FAv mfg DML, fav kit Night fighting panther aus G
Aircraft _ FAv MFG Tamiya and Hasegawa .. fav kit Hase AV 8B
Paints - fav MFG Gunze Sanyo...
this is my opinion in general, since all of the them are available here...as for DML their price were very reasonable here in Malaysia. AFV Club also comes to mind but not so many of them were stock at local store...their price is good also..
Tamiya i think the mainstream of the kit here in malaysia..they have thier local sole distributor here, and the agent had setup a network of thier stores across the country - they call it Tamiya ToyCity. Hasegawa are hard to find here...they're a bit expensive ...
but anyway this is my opinion..thanks for reading it
