I am much more of a preferred "player" from above, at least originally, but I had to change my playstyle in 4 to even it out. Live mode just doesn't hold my attention like in the other entries (where I would CAS, BB, and then be in live mode nearly exclusively), so I hop around a lot and spend basically an equal amount of time in each (with no linear pattern anymore).
4 BB and CAS are great. Live mode still feels lacking to me, so it only makes sense for me to engage it using its strengths to have fun.
