If I could point out something fairly obvious... I find as both a player and DM that a mixed group of foes is far more interesting. The key reasons are variety and strategy. If I'm facing 5 identical foes there no tactics at all. Attack the closest one to me, flank if you can. If you're facing a set of monsters with a variety of types, hit points, attacks, roles, that gets juicy! Do we take out the striker first? The leader? If so how do we get 'past' the brute? Go after the high damage striker first, ok then, who? Have the defender nail him in place? Gang up on him? Send your own striker(s) after him?
There's so many more interesting choices to make versus a mixed set of foes. Same thing from the DM's side of the screen rather than making the identical attack fives times.
Mixed foes (combined arms) are definitely the way to go!

They were also much poorer in tactics at the time, too (they're still learning more about combat advantage and powers that aid another) and it showed. Our characters leveled up, and so did the DM after that session.
