I am with MacB, I have been on toeclips for about 25 years, in 2007 I had clipless on my best bike for about six months, and hated them, I also got no benefit from using them, it was no easier, I was no faster and didn't climb any better,after six months I went back to toeclips.
I'm the same (only it was longer in the clips

)
I think this is a case of each to his/her own.
I gave clipless a fair trial, for 2 months and about 400 miles, and had two clipless moments - had a couple of clip moments when I was getting used to them years earlier so no difference there.
I hated the feeling of being attached to the pedals, and didn't like being restricted to one pair of shoes which weren't much good off the bike.
I agree that there's an advantage with clipless when putting in a lot of force on the pedals, but not much. If they'd been around when I used to do time trials I'd have used clipless for that though.
I'm back to pedals with toe clips, much happier with that. If I'm going to be on the bike for any time I use a pair of Lidl trainer style cycling shoes with the flat plate screwed on. They're shockingly good for the price! The rest of the time I can wear whatever shoes are sensible for what I'm doing when I get where I'm going.
I also find the mtb type clip pedals with no straps good for around town. Can't imaginine what it's like using cleats when you have to unclip/clip 20 times in half a mile.
