It depends of corse. Playn´ stuff like rock and metal, bass might be easyer ´cause you get rid of solos and stuff but playng stuff like Dream Theater, it can be rough. We have an amazing bass player in our band and when we´re playn´ somthing (fast riff) by Theater my hand movement is so little but he´s is so big because there´s lot more space betwen frets on bas. So it´s prety hard to play fast there.

Than al this picking with finger seems amazing to me. I suggest you to use 3 fingers instead of normaly 2.

When it comes to extreme stuff bass may be more difficult when playn riffs.
