Revell has some good stuff. Sure, it's lacking in detail, but any chimp with a knife and some plastic can fix the shortcomings therein.
I'm kinda scarred from the AMT Fruitwagon's multipiece cab and a lot of flash, but their older kits were good. Back around 2004-ish, I built a handful of AMT/Ertls, and never had any complaints. Maybe I'll try their new Ranchero out.
Moebius has nothing that is too interesting to me, although it'd be cool to make the Fabulous Hudson Hornet.
Tamiya is wonderful. I've only built two of theirs, and they were both Minis. Great parts fit, no flash at all. Some little mold pins, but that's about it. Everything fits nicely and has crisp detail. The decals are great. Great little "no-worries" kit. Their replacement policy is great, too. I had a malformed brake drum on one of the parts trees, and they replaced it and the roof at no cost!
