Correct me if you have more experience, but I have mostly avoided using smart plugs for computers because the PSU capacitors generate a large inrush current which tends to weld the relay contacts over time, causing the plugs to fail prematurely. Maybe ok in a power loss scenario, but not good to use for remote waking regularly...

Modern ones that are rated for it are fine, you might need to replace it after a few years, but they're cheap. Thousands of cycles for a 15 amp device.
