Generally, linear. For simulation in vacumm, you need rotation.
With big molecules, equilibration may not be done thoroughly; this may result in very obivious rotation that Linear can not prevent. So visualize your trajectory and check your molecule. If it happens, you need to apply Rotation in the beginning of your simulation for a few ns.

Subject: [gmx-users] the comm_mode
There are three options of comm_mode: Linear, Angular and none.
The option Angular is said that "Remove center of mass translation
and rotation around the center of mass". Does it mean the option
Angular remove the translation and rotation BOTH ?
If I want to do a simulation such as a protein in the explicit
water, which option would be better? Or it will be the same?
Thank you for your reply.
