I hike nearly every day lately, and my favorite hiking pants are full-length, loose-leg styles from Athleta. I also have ones from Zella, REI, and Prana.
I’m thinking of getting another pair from Athleta because the old Zella ones are wearing out and the Prana ones have a weird drawstring closure in addition to the button/zip fly, and it’s a little annoying to use, but the waist is too big without the drawstring. All of these pants are several years old.
My requirements for hiking pants are pretty specific though, so YMMV. I usually want full leg coverage because I sometimes go off trail or sit or crouch on the ground to take photos. I need pockets that are nice and deep and preferably zip closed too (for spare memory cards, etc).
I also have a lined pair of fleece-pants from Eddie Bauer that are great for winter!
Good luck!
