I've built Trumpeter's 1/16 King Tiger and Panzer IV, both with full interiors. I also built Das Werk's 1/16 Stug III with partial interior.
All are quality kits that went together well, around 2,000 parts each on average.
I got threads on each one in the Armour section here on the forum.
That's all the 1/16 kits I've built so far, and I would recommend all of them for what's it worth.
