I have been looking forward to running Haiku as a daily driver for years. And it is almost there. It may even be good enough now for many people. Modern browsers really help.
But I was amazed recently when I put Haiku on an old laptop that was already running Linux. I remember Haiku being so lean and fast and multi-tasking so smoothly. But honestly Linux felt faster on this machine. The memory usage was about the same (a real shock to me). And I missed being able to use containers. So, I ended up putting Linux back on.
This bummed me out because I have been a Haiku fan forever and it has never been better. But when I tried to use it, I could not convince myself there was any benefit (other than diversity). And the reason had nothing to do with applications or drivers.
