I'm probably not gonna make any friends with this post, but here goes...
1) The Might & Magic series as a whole trounces the Wizardry series. Every Might and Magic release since the first one is superior to its closest Wizardry contemporary, with the sole excepion of MM9 vs Wizardry 8.
Even what most people consider the 2 best entries, Wizardry 6 and 7, don't hold a candle to MM2, MM3 and World of Xeen.
Wizardry 6's sole tile set is gray stones, even you go into a "forest". They had time to draw pixellated boobs, so they had time to draw a decent 2nd tile set. MM1 came out in 1986 and had 6-7 different tile sets! And I'm not even mentioning MM2 which came out in 1989, also before Wiz6.
Wizardry 7 makes you fight (or talk to) annoying rat men for the entirety of the game. I swear for a super long game, most encounters are either rat men, orcs, or those blonde chicks on hover bikes.
