There's nothing 'wrong' with CbB. I too jumped on Studio One Pro before Bandlab and found Version 5 to my liking (keyword: workflow).
Before CbB, Studio One had arranger track and so that is my workflow now. I tried CbB Arranger it's not my cuppa since it goes about it from a different angle (to me).
Studio One has a decent chord track and chord detection system going for it.
Studio One allows free form placement of Busses in the mixer (i.e. not a fixed place for busses only). A bus can hide/show its feeder tracks. I find that nifty.
Studio One does not have as powerful MIDI editing paradigm IMO but I do so little with MIDI these days it's not a burden to me.
