Personally, while I also love 21st Century/Ultimate Soldier, I appreciate the fact that Forces of Valor (FoV) is still offering 1/32 scale vehicles. I really like all the ones that I own (although my collection is rather limited). I'm waiting on the re-release of the 105 mm howitzer and while I've thought about getting into the more expensive 1/30 scale brands, I enjoy my 1/32 scale vehicles and figures. My only complaint in regard to FoV is the cost which seems a bit high for what you get, although I love the more metal vehicles.
That amphibious vehicles looks pretty slick.
