I love them once they're on, but I hate putting them on. So clingy, and it just takes longer than throwing on some old regular jeans or sweats. I'll ride in anything and everything. Shorts included. Just throw on my half chaps, and I'm good to go. It's a bad excuse I know, but I just prefer to go without tight things, unless I have too.
I have tons of pairs of regular breeches that I really should use more often, but again, I hate putting them on. I have my tan ones for showing and clinics and stuff, and like three other pairs in funner colors, for a reason I don't know why I have them. I think they were all like birthday gifts or something.
Also think it depends on where you are. Barns tend to have their own "style". At all the barns I hang out at, it's jeans and half chaps. So... I guess that's where I get it from. We all like to take our chaps of immediatly after the ride, and just hang out for awhile, and I can't see myself wandering around in jeggings without my chaps on.... I've never been one to wear tight things, unless there's chaps or tall boots involved. Evens out the look for me.
With this new saddle I'm getting though, I've heard jeans can rub the soft leather too much, so my opinions on this may have to change.... But we'll see. I may become a jegging fan.
