On linux a lot of the time you kinda have to shut down because it either won't go to sleep ("failed to freeze" some process or another) or it will hang or lock up during/after wake - especially if it has nvidia with its binary blobs, but i've had problems with (in kernel, open source) network card drivers too. Since I first had problems like this with linux 2 decades ago, it seems like they will never be able to figure it out.

Some of this seems to be getting worse with the move to wayland. There is no design concept like windows D3D device reset or lost device, or display timeout/recovery, so drivers are apparently charged with perfectly remembering all the state that compositors create, through all the sleep states, with predictably bad results.
