After reading 3 pages of pure confusion I feel the need to post(after 6 months of reading xD).Hi BTW!
So, my point of view. Your streaming speed is only as fast as your slowest finger, and if you can singletap 300 with 1 finger and 200 with the other(not by using your wrist...because alternating needs you to move your both fingers you can't lock them like people do when singletapping), your streaming will speed still be 200. So training one finger is not enough for getting better at streaming.
I think this not only says that bigfeh's wrong but also that alternating might even train your speed faster.
Now answering the OP (if anyone's still interested in it):
As an alternater I don't think it can handicap a player. Sure you might have a hard time doing triples at the beginning but I from my experience it makes very relaxing to play faster 1/2 spam beatmaps where others might just tap like crazy (so better stamina) and also makes easier to start a stream or basically any pattern on either finger. I'm sure it is not worse than singletapping so as long as you don't feel that you have to learn singletapping you don't have to switch playstyles.
I already feel better xD. Guess I'll try to be more active so say hi to the newest forum user.
