id say if you are technically apt to do so and enjoy playing with your phone, then do the tried and true method.
If you dont want to spend too much time and want a quick root and dont want to spend tons of time reading and diagnosing problems you may run into by not understanding things or following directions. . . do unRevoked.
I did unRevoked on two ocassions and was a 5 minute deal with no hangups. Works fine for what I needed it for.
