It all depends on the situation. A hardtop is generally tougher, harder, and more durable. A hard top is what you want to use during winter when you need something to insulate your vehicle’s interiors from the extreme cold or the snow.
Soft tops are better during spring and summer. The advantage is that they’re easier to install and remove, and some come with sunroofs so that you can roll back the upper part and enjoy the open air experience.
