About other companies doing better versions, I think Academy and Tamiya are just easier to come by, especially if you shop local. Now, in my mostly-internet-lectured opinion ( meaning take it with a grain of salt : it's just an opinion based on research) :
- Dragon's big kitties are looking good, finely crafted, often with engraved zimmerit, photoetch and sometimes aluminium barrels ; but the price tag goes up and here in Belgium they seem harder to come by... but I think you often get a great kit for the same price as a Tamiya kit with basic aftermarkets, or even cheaper.
- while looking for a Panther type A late, I considered the overdetailed newcomers : Meng, RFM, Takom, Hobby Boss, but shyed away : I had no interest for the full interiors and the multipart single link tracks were a dealbreaker for me (lazy me, I know, but it quickly kills my interest ; I sourly remember Dragon's dreaded 3-parts Sherman tracks when I got the Firefly in my teens) ; for what I'm looking for, they look overly complicated, butcgreat nonethless.
- I saw AFV Club got Tigers but have no good info about it. I'm curious, though!
