[Freezing Rain] = [Sleet]?

Are these two powers pretty much the same exact thing? The only difference I can find is the level they become available.

It's always been my understanding they are essentially the same, yes.

Corruptor Sleet, Corruptor Freezing Rain, Controller Sleet, Controller Freezing Rain, Mastermind Freezing Rain and Defender Sleet are all effectively the same, though different pets are used for most of them.

Defender Freezing Rain has a higher speed, recharge and resistance debuff than the others, though.

Freezing Rain is better, because I play Storm :P

Sleet is better, because most stormies are bad.
