Overall a very nice fighting game. It would be better though if it had more super/ultra moves (Street Fighter Alpha 3 had around 3 different super moves per character...). You may get bored executing the same super/ultra move over and over (not to mention that depending on the circumstances other moves would be a better match).
The collectors edition package is not anything great. It has two average quality/detail figures, a useless booklet with some moves for the new characters and a bluray anime movie (haven't seen it yet). My point is that it does not worth much more money than the standard version, so buy it only if you find in a good price (like i did!).
