There's an important question you haven't answered: what will you be using the distro for? Answer me that, and I can tell you what would likely fit you best. Most people don't realize that the majority of Linux distributions are very similar, with small differences you can change anyway. If you want the distro to be heavily customized to your liking, go with Arch. If you're not willing to go that far, install vanilla Debian or Ubuntu and customize it to your liking. If you like minimalism, #! will work wonders for you. If you like bleeding-edge updates, Manjaro is Arch for lazy people. I'm personally about to buy a ThinkPad to dual-boot Ubuntu with LXQT on one partition, and OS X on another. I asked the same question quite a while ago, feel free to take a look.
