I think it just varies, but I'm with you. It might be because I also wear glasses, do you? I feel like the ear loops press my glasses harder into my ears, preventing longer term wear (they're great for a half hour, not so good for six hours straight).
I mostly use behind the head but foldable ones now, the ones to TC-84A-9315 spec (H95W) are pretty good for me but my nose is a bit too pointy to fit right at the nose. They seem to work really really well for people with slightly flatter features, the little nose metal form doesn't quite hold well enough.
