I have used both on a few different cars and I personally like the E-cam. The B-cam just doesn't seem to start pulling till later in the RPM band compared to the E-cam. I will add that I have always installed them straight up so it may work better with some advance. Didnt have problems with either one dying at lights or anything goofy like that. Neither one will sound stock by any means but the B definately has a lumpier idle than the E. Now that that is out of the way, if I hax X amount of dollars to spend on any cam in that price range, I would probably give the TFS stage 1 a shot. Have heard nothing but good things about it but I have also never had a chance to try one myself because I always seem to happen across brother-in-law deals on alphabet cams and I imagine thats where you are at as well.
