Are non-TSA padlocks better than TSA-approved locks for travel?

Specialist communities like r/onebag and r/travel consistently argue that TSA locks offer minimal security because master keys are widely available online, while a non-TSA padlock can deter casual pilfering more effectively. The trade-off is that if you check a bag in the US, TSA can and will cut a non-TSA lock to inspect it. Non-TSA locks make most sense for hostel lockers, carry-ons, daypacks, and bags you keep with you.
