Hard to mix "Stalingrad" with "Enemy at the Gates" - former is a (anti)war movie, latter is a western with war theme.
As to Stalingrad, watched it again not so long ago, it's still very... good movie, Vilsmaier's pearl. What I found new about it is this precise attention to the details.
Enemy at the Gates is still also a good one, but it's... well, in the town, overcomed by bad guys (Germans) the good guys (Russians) found good gunslinger (sniper) who kills bad guys. So the bad guys send for a bad gunslinger to kill good gunslinger. Hello, mr. Leone
It's why I like this movie, great pastiche, and really nicely done.
