I'm probably an odd duck.
I know a guy who plays piano as good anyone I know. A professional entertainer. This guy smokes. My gosh, can he beat out the boogie. Awesome. But... after one or two sets, I've had enough.
If he were playing an arranger, I likely wouldn't tire of it. I don't know that, I've never heard him play an arranger. In fact, I never will, because he never will. But I'd be less apt to tire of it.
Secondly... if I played an arranger and could play really well, I would definitely do what Esh said, play piano-only tunes several times a night.
