Once you are at the level of performing it, it doesn't matter. How hard do you want to work at home creating it? I prefer Real Band because it is a 48 track sequencer with the value add of being a composition tool. Create your stuff from a style, add your sweetening tracks, and go. For live stuff (I have done little but I have done it - only songwriter night when I got 3 songs) I saved my songs to wav files with the vocal track removed and just played guitar and sang along. I played the tracks from my iPad plugged into the house sound system.
