Justin My overall priorities include Modern Hardware Support (HiDPI, touchscreen, accelerometer, stylus), Desktop Integration and Ergonomics (UX), Package Selection, and Community Support.
Manjaro's appeal is the focus more on user community and stabilization of the varied Arch packages, that give you a much wider array of software rolling release, rather than Solus' strangely "curated" approach. I also don't really know Solus' focus, or actual target market. Maybe I should give Ubuntu Budgie a chance 😄
For example, my first touch point to the community: Solus flat rejected Firefox Developer Edition to the package repo, even though it really is a separate tool (I am a UI Engineer for Red Hat, and I concur, it's my go to development tool after code editor). https://dev.getsol.us/T5781
I thought the responses from the community in that thread were respectful and comprehensive, additionally a community member offered to build and maintain the package for Solus.
And the response from the Solus was team was "You can easily just download the tarball.", which like...you could say for basically everything. 🤔
