Which is the best provider when it comes to running a freshbook software?

Both the options are good. SSD Windows VPS provides better performance as it can handle better disk I/O (10 to 50 times more than traditional storage) while Cloud Windows VPS provides better uptime.

Though I would recommend selecting a provider who gives complementary backup which can be a lifesaver during difficult times. The other points should be like 24/7 live chat and ticket support.
