I see no reason for brand loyalty. Use what you feel fits your needs, regardless of brand. Before Arrangers I had a full Korg setup, drum machine , two keyboards and bass pedals. Then my first Arranger, a Roland RA 90 , then on to a RA95, G1000, and now BK9. My reason for staying with Roland is I'm too lazy to learn a new system and redo all my songs to fit the new Styles. I hate the time I have to put in editing now and I know my way around the BK9 pretty well. Whatever floats your boat.
