Are snuffle mats or treat-dispensing puzzles better for fast eaters?

Verified-purchase and community reviewers generally point fast eaters toward snuffle mats and wobble/dispenser toys because both stretch a meal out. Multiple r/puppy101 and r/Dogtraining posts note snuffle mats are 'easy mode' and can be emptied quickly by determined dogs, while screw-apart dispensers tend to slow eating longer but are noisier on hard floors.
