While turning off never makes really remarkable issues, except for maybe hardware degrading a bit faster, the sleep mode p*ssed me off numerous times with even some buggy things at some startups and the hibernate mode seemed rather useless, so I simply have quit it with them. With an SSD and W10, I don't feel much slower than if using sleep/hibernate, so both are things I've turned off from power management and I don't use them manually at all. And if there аre thunders/electricity issue and you don't hear/know about it, you may really feel like you wish you had your PC turned off, otherwise you may wonder why your internet doesn't work or motherboard restarts itself whenever it wants.
