Wedges are fried often times. At our nation-wide supermarket for example, at the ready-made counter, wedges are definitely fried. Same with the mom and pop chicken shop down the street.
Air fryer makes sweet potato move up the list, regular oven makes tots go up. Traditional deep fried makes them go down and brings the potato items up.
I think the OP was originally about fried preparation of potatoes. Wedges at least in North America are usually fried, I think the only non-fried ones I've seen are in the UK.
Also if we're talking about the best preparation of potatoes in general, it's mashed and there's no argument there.
