Desperados or Commandos?

Hey, I have played Desperados: Wanted Dead Or Alive...and it is the best Real Time "Tactics" game for me.

Of course, AOE 2 is the best Real Time "Strategy" game though my friends say "Civilization 4" is better but...meh.

Coming back to the point, I've heard that commandos has many problems like (1) not being able to save properly or at all... (2) No tutorial...game crashes if tutorial is clicked. (2) And very poor interface.

But still I hear few people tell that commandos is better than Desperados.

So in which commandos game were all these bugs/glitches removed and proper saving mechanism was implemented.

Which is the best commandos game (there are 3 "tactics" and 1 "third person shooter" ) with proper interface and tutorials.

I think I've played the original commandos (WW2 era in snowy berlin and such)
I don't remember any problems with saving or tutorial... But same can be said about which version it was exactly, it could have been 2 or 3 just as well as original. The graphics are of course dated by today's standards, but the game is fun if you like the style.

Looking at the wiki I think it was the first one, but I'm not 100% sure
