SSDs boot a lot faster than HDs. But they probably won’t last as long, and generally there is far less on-board storage. If you are happy giving your data to Microsoft, Amazon, Google, or one of the lesser ‘cloud’ competitors, then SSD is probably superior. If you want to keep your data close to home, get a HD and an external HD for backup.
The ideal setup would be a blended system - SSD for boot and programs, HD for data storage.
Since these are laptops there’s no way to install two internal drives, and the org I work for won’t let us have external drives. That said, the entire hard drive is never used (maybe 25% ?) and the few folks who have the SSDs swear by them.
