My last router table I installed t tracks onto and used those to clamp my fence. My newest table I've gone back to clamping down. I didn't dislike the t tracks but the clamps are simpler and I think they hold better. If I change my mind I can always add them later. There really isn't a right and wrong answer, it just comes down to preference.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
