Barrel rifling

Ordered a barrel and was asked 5 or 6 groove rifling. Going to sound stupid here but what is everyone shooting? Does it make that much of a difference? I’m far from a professional. Initial research claims bullet/jacket deformation with 6 groove. I watched the bartlein video and he says 5. Everything seems conflicting so looking for info from folks who use and know this stuff. Barrel is a 26” heavy varmint 1-8 twist chambered in 6.5 creedmoor. Thanks in advance.
