It really depends on your experience and skill level. I’ve been using unix in one form or another since the mid 80s, so i do a manual install. I know whats installed, where, and how, but I’m a little bit of a control freak when it comes to my systems. I have dual monitors so i can open more xterms.
As a fellow noob not too long ago, my vote is Hassbian. Simply upload the OS to an SD card and pop it in. Also comes with scripts to install extras like zwave, although you’ll need a z wave dongle for that extra to work.
