I'm thinking of buying a mazda mx5 nd but i don't know which to choose between the RF and the soft top.. i want to use it daily.
If a daily driver? RF.
F.S.
A hard top is better for daily driving.
I would choose the RF because you mention daily driver. Generally a hard top will provide better crash safety, more noise/weather insulation, theft-deterrent (compared to soft top), don’t have to worry about replacing the top (softops usually don’t last as long as hard tops). The downside is higher price, less room above your head (compared to soft top), cargo space, weight, longer up/down time (for hard top). I would test drive both and confirm which will work better.
Here is the flip of all that (to get a different perspective - courtesy of Engineering Explained):
