I've been staying on iOS 17 and macOS 15 because I just don't see iOS/macOS 26 as an upgrade in any way. This is the first time I haven't been running a beta or getting a day one upgrade for Apple operating systems. I can't imagine moving away from iPhone or a MacBook, however if they want to avoid OS fragmentation and security issues caused by users like me refusing to upgrade, 27 better address these UX and stability issues.
