GR is a very viable offensive champ, with excellent regen, nullify, power drain, fury, and bleed. If you get the hang of him, he can be incredibly useful.
Mordo is a decent defender, especially if you have MD. However, we're all getting very used to fighting against him (not only in AW, but now as mini in AQ). Not to mention, other alliance members probably have him ranked for defense, so you won't get the diversity points there. Offensively, he can stack fury quickly and do a lot of damage, but he takes quite a bit of damage as well, and there are better offensive champs to use (like GR).
UC is a pretty over-rated char. Unstoppable is nice, but it is pretty short, and he has such predictable move-sets. The only people getting killed by him are from Android lag.
