Well, on my laptop I actually run Debian. So, I suppose that would be my default answer. That said, I'm running Debian on my laptop more because I got used to it, and already have it configured how I like it rather than me actually having enjoyed the experience of installing it / getting it configured.
Thus, if your question is more about what I would switch my main machine to in the apocalyptic imaginary scenario in which Solus disappears, then it would be a different answer. In such a situation I think I would probably be looking at Fedora (I've heard some good things about its stability and up-to-datedness), or Manjaro which was actually the first distro I gave a proper chance to. While I hated Manjaro when I first tried it, a lot of that hate came from me not having yet learned the difference between desktop environment and distro. I was using the - at the time default choice for Manjaro - XFCE desktop and really reaaaallly reeeeeeeaaaaaaaaallly didn't enjoy it at all (and still don't). I was also not really prepared for the finickiness of Arch. As a much more experienced user now, I would probably be able to handle it a bit better than before; though, definitely with the KDE desktop this time.
That said, If I'm being honest those above picks would really be emergency, apocalypse, last chance before the sky starts falling, choices for me. Using a distro other than Solus is fine on my laptop which I only use for very light occasional coding practice, online chess, and hulu watching. Actually having to switch environments for my main machine would be terrible. I would be a little lost without Solus quite frankly.
