I don't have experience with the Alesis, but have had electronic kits from Simmons ('eighties) and currently have a Roland. The Roland is a very nice kit and the companion amplifier (sold separately) is the very best I've ever used with a drumkit.
Electronic drumkit drumming is very different from acoustic kit drumming. (I've had Ludwig in the past, have had a Sonor kit for over 25 years now, not used much the last decade.)
