What's best for what?
For DPS? Raiding into T5 content, ele will do more dps, t5 on, enh will start to do more. I'm a noob in t6 content and still get beat by our ele though... WTB drops and less rogues and hunters...
Really just depends if you want to be a caster or melee, elemental is (don't shoot me) easier to play (not having to stay in contact with mobs as much) but you'll probably get called to off heal at some point, you get to cast two spells, enh, cast 4, plus totems for both...
I had a spriest as a caster, I wanted melee, my choice was a rogue or shammy, went with the shammy just because it was new and different (alliance), rogues out dps me though, but to your orignal question, thats the great thing about hybrids, try them both, you can always change without rerolling
