It's kinda ok.. My work iPad is 6th and I did install 17 on it and my work iPhone 13. The iPad was already getting a bit slow and I don't really use it much.. I've held off installing 17 on my personal devices.. My 2015 MBA isn't supported above Monterey and I'm leery of updating personal iPad and iPhone further fearing they may not work well together anymore. I may do it later in the year once it seems these bugs/security issues in 17 have been worked out.
Do install the iOS 16 updates apple is still releasing, though, for security. The latest is 16.7, just released on the same day as 17.0.1.
