Ive had my Sensei for about 4 months or so now. It's been myfirst 'gaming' mouse and a serious upgrade from my standard mac mouse. Things that I really like about it are the onboard custom profiles, to change different settings around. It's very comfortable, and I think its improved my play significantly, just because I can be more accurate.

My only complaint is that sometimes it handles very weirdly, and Im not sure how to describe it, and it could also be a result of a dirty mouse pad.

I've not tried any other razer mouses but Im sure their good mice aswell. I think you should try and get your hands on both and test them out, and go from there, but I would strongly reccommend the sensei either way.
