Thanks for the feedback guys, everyone pretty much said what I thought was true in regards to Alpha strikes, screens etc.
I definitely think at the moment I will probably curb the elite army idea, I haven't painted a horde army in forever, so meh, just get over it I guess.
On the different armies people have suggested:
Dark Angels: Deathwing and Knights especially are pretty resilient with the 3+ invulnerables from storm shields and were the Space Marine chapter I was looking at because of this. There are pretty decent horde clearing weapons across units, but I think only the flyers interest me in that respect and I can probably expect to be tarpitted at my opponents mercy.
Harlequins: I really do think these guys would deal with hordes pretty well considering, regular troupes are filthy good in combat, but as someone mentioned I think I would get upset that my painting skill doesn't allow for diamonds XD
Orks: shooting is hard and with all the -1 to hit thats floating around, its even damn harder, some of the vehicles character and the psychic power combo for movement really makes it hard to resist.
Tau: If close combat wasn't restricted to Commander Farsight, and with all the alpha strike at the moment I really can't see what they are going to do to fix this shy of making some combat suits (CAN ONLY HOPE THIS HAPPENS!!

)
I guess the only thing I can do is mull it over some more, build some more lists and see what list I find the coolest.
