It's hard to say. I've never been in a car with them. Although, some Corvettes have been using them for several years.
I have the same shock and spring setup as you and it can get a bit stiff at times commuting 70 miles a day but I've done it for 65,000 miles. If I do decide to jump in for a GT350 it wouldn't get driven nearly as much so a potentially stiffer ride wouldn't bother me very much.
