Do note, RCS can be a bit of a bitch (might have to disconnect your old phone from your number, read the RCS forum thread if you have issues), some banking apps don't work (really just depends), and you can no longer use Google Wallet/Tap-to-pay (but maybe that's a privacy positive). These are the only major issues that might hold you back.
Otherwise, use GOS installer on their website (use a Chromium browser! FF breaks it) for the easiest ROM of your life.
