You’d be safer from lightening in a hard-top, but not that much. It’s very unlikely you’d be hurt by lightening strike in either configuration. The soft top wouldn’t be nearly as safe as the hardtop in event of a roll-over of course. That’s probably the bigger concern. There was a lot of lightening in Colorado where I used to live, and I never heard of anyone being hurt b/c their car was struck by lightening. Some cars were damaged b/c of that, mostly parked cars with nobody in them, but even striking an occupied car, I don’t recall hearing of anybody being hurt. Not to say such a thing is impossible of course.
