Thanks for understanding, no hard feelings. It's sort of ingrained into people so you can't really blame anyone.
Anyways, the mtb pedals are smaller and shed mud, but the road pedals are larger and offer and bigger, more comfortable platform for long rides. However, mtb shoes ofter have recessed cleats so you can walk around with ease without clacking around and walking like a penguin. If you're doing longer rides, like idk 30+ miles, I'd suggest road pedals. If you're concerned about short rides, you can just ride on the bottoms of the pedals and it's really not so bad as long as it's only a few minutes.
