Every time!
Every time!
I remember when windows used to brag about incredibly fast boot times.
Now, my 5 yo gaming PC takes about 30 seconds to wake up to the password screen. While my Linux laptop takes 15 seconds to go from cold start to desktop.
For me I can reach the windows desktop in around 14 or 15 seconds (auto login), for most people the biggest bottleneck is a slow bios.
Linux and windows normally have very similar boot times at least on my hardware.
