GitLab is starting to become difficult to use due to the amount of features being introduced. It was simple but now it just looks and feels complex. Personal perspective, of course.
Meanwhile many core features are still unpolished e.g.: running your own runners sucks and you can't test CI/CD locally.
Also, I find that running your own runner is super easy and straightforward.
Then again, I also find Facebook and Twitter so confusing they're nearly un-usable, so maybe it's just me.
GH and their clones are fine, though GH's starting to nose into "too much shit going on for me to make sense of it, and unhelpful information density/hierarchy" territory after the last major re-design and latest round of updates, too.
Oddly, very complex actual desktop applications with tons of features rarely leave me feeling helpless and lost the way business productivity web apps so often do, unless they're something like Blender.
This reduces the menu items to a minimum.
