I installed it almost a month ago as the boot sector somehow got wrecked when shrinking the partition and got those three words. It was a bit unstable in the beginning and I'd probably put that down to systemd but it's been rock stolid since then. 

Been running Fedora 25 for a couple of months now with no major issues.

Only serious problem is an intel video bug when running a rotated portrait display.

I upgraded one of our laptops (which is HiDPI, over 250 pixels per inch) from Fedora 24 to 25 shortly after 25 was released, and had a lot of problems. Some of them settled down with further package updates but some remained until I changed the display server from Wayland to Xorg. Since I did that, Fedora 25 has been as stable for me as 24 was.

Perhaps Wayland problems have been fixed, but I haven't tried it in weeks. I'm happy to stay with Xorg for now.

Fedora shows quite a bit of potential however am sticking to Arch as a desktop distro for now. It seems every time I try Fedora it seems like a beta.

Wayland seems to show a lot of promise but it doesn't seem quite ready for general use just yet.  I upgraded both my workstation and laptop to Fedora 25 a few weeks back and was surprised how flawlessly it all went.  I'm still using Xorg though as a few things that I depend on for work don't run properly under Wayland (colour pickers for example).

Other than that Fedora 25 has been working great for me.  I was having some issues under 24 with Gnome Online Accounts which have been resolved and Gnome 3.22 has added some useful features.

I don't think Nvidia are supporting wayland just yet but they're getting there. I wish they'd hurry up as X is getting a bit long in the tooth. The only other thing to grumble about is system settings segfaults more often than not.

I'm running Fedora 25 KDE on my work laptop, so I don't get to [have to?] deal with Wayland yet. The release itself is strong one. No complaints. 

Generally, with Fedora, I wait a few months after release to upgrade. I figure you can't possibly avoid all the bugs in a cutting-edge distro, but at least you can avoid the big obvious ones that inevitably pop up just after release..
