15.3 final seems to be running great for me so far. I’ve noticed that my 13pm feels more snappy and responsive and I wasn’t even thinking about the system responsiveness. I’ve just noticed that apps seem to open much quicker and iOS in general feels more responsive.
I updated from the RC. I’m thinking of doing a wipe and fresh install now that 15.3 final is out. I haven’t done a full wipe and restore for well over 18 months, which is unlike me. I usually always perform a fresh install of a new operating system on every device I own. I’ve always considered performing a wipe/format and fresh install of an operating system to be a good standard practice.
I’m going to leave things for a few more days to see if any bugs pop up.
