Adding to what josephcsible said, not just tiny but also super simple. I use Alpine on all my routers/firewalls/VM's/physical servers for personal use. I've been very happy with it thus far. Simple upgrades. Easy to debug. All the packages I use appear to be compiled with decent hardening options. The LTS kernel is just a few days behind kernel.org.

I've not tried to use it as a desktop. I alternate between Void and QubesOS for desktops.
