From my decades old recollection I think it might have been better. They didn't have the little touches like losing morale and running away like halo, but their combat tactics were very dynamic.

They wouldn't get stuck in a loop repeatedly peaking from the same piece of cover, they'd take some shots from one location and relocate constantly. And seemed like they were weighted to coordinate so that they would prefer to move from cover to cover when another was firing at you.

[Edit] oh and looking at some gameplay videos to confirm, they also had the nice touch that the last squad member standing wouldn't call out everything to a roomfull of corpses. Not shouting "grenade!" for just your enemy is an Einstein move for your average FPS grunt.
