Well, we're all different. I've been riding since college in the '70s, back when only really serious cyclists even used toe clips (they were "too dangerous" because you were "attached to the bike"). I've been through three or four types of clipless pedal systems, and about three years ago gave them all away and went back to clips. I've done the same 25-mile round trip commute for more than 30 years, on everything from racers to recumbents, and I wasn't any faster with any of the clipless setups than I am with clips. And if I just want to ride down to the store, I can do it on any bike in any old shoes I have on.
