Your car's towing capability will dictate this more than anything else. You didn't say what your vehicle is?
For example, my 2013 A3
had to be a 1 1/4 hitch because that's what the car is rated for towing (Class I). My 2015 Q5 has a 2" hitch because it can tow more (Class III).
Go to etrailer.com and plug in your vehicle's specs. Go from there. This isn't one of those debates like 27.5 vs 29 or disc vs calipers. You go with what your vehicle can accommodate.
