While I do enjoy Tamiya aircraft, I'm not a fan of their armor.
Halftracks: Dragon while they are a pain to align they are far better and more detailed then what Tamiya offer.
King Tigers: Meng and Takom best out there right now and at a better price compared to Dragon and Tamiya Panther: Same Meng and Takom
Tiger I: Rye Field Models new Tigers better kit and better price.
If you just want something that will build fast and easy go with Tamiya but if in the end you want a very detailed and accurate model go with the above.
