Fixed rails
(+) Lighter table. 4 bearing blocks are far lighter than two rails.

Surely a lighter table is a minus. Vibration is the enemy and dead weight dampens vibration.

Same goes for the gantry, bolting it to a dead weight reduces the rattle.

Power to move a heavy table/workpiece ceases to be a problem the moment you start using ball screws. You get an enormous push.
