A big concern is "usable light".  
LED's and T8 lamps look bright, but they look bright at the source or fixture vs a T12, that is deceiving.  
The T12 while a larger diameter, throws/disperses the light further.  It all depends on how close your fixtures will be from the table tops, floor, splashing on the walls etc.
Pay the extra money for Tri-phosphor white lamps, their 30 to 40% brighter, and they'll stay brighter longer twice as long, if not longer.  You won't regret it.
