I think it might be hard to go past Web for the battlefield control.Also, I'm still undecided what spell to take for my first 2nd level spell to alleviate our lack of area effect attacks...
I'm currently playing in a live group in the World's Largest Dungeon. The sorcerer player is usually of the 'he who hits hardest wins' camp, so I was quite surprised when we were able to convince him to take Wall of Ice and Wall of Force spells - I can't begin to count the times that they have not only allowed us to control the battle, but have quite literally saved our hides on a number of occasions, ie to flee!
The player also now recognises the value of battlefield control.
