This is funny because I also have both and have almost the exact opposite opinion.  My fire stick is smoother, less buggy, and has a superior remote to the roku.   And the form factor is about 1/3 the size.  The Roku interface is easier for my parents though

There are a lot of Roku products, my streaming stick is smaller than my Fire TV stick but not by much. Maybe you have a bigger one. I do like that you can easily put Kodi on the Fire TV stick too and screen mirroring works great on Fire TV stick.
