I don't have strong opinions on most of these issues, and I'll play on any table that lets me win more chips.
But since you asked, I prefer:
- no wood race track
- if custom cloth, then a betting line or a diferent color dyed into the felt to emulate a racetrack
- no cup holders, but if you had cup holders, then not in the rail
- more-padded rail, rather than thinner rail
- full rail around, not with a dealer cutout (unless you always have a dealer)
- ideally a custom logo felt rather than speed cloth
