I've previously used versions 1.4.* and 1.5.* quite a bit for print, because I'm a one-man marketing department in a tiny company.

Scribus was (is?) somewhat finicky and cumbersome to work with. It had certain quirks and workarounds you had to learn to deal with. It lacked many creative features you find in bigger suites. I didn't feel like I worked quickly and efficiently in it. BUT I got my work done in it nevertheless, and I really appreciate that it exists for the people that simply can't afford the alternatives.

Nowadays I use the Affinity suite, which includes Affinity Publisher, a competitor to InDesign. It's quite affordable and not subscription-based.
