When I had a soft top and had to open the back all the time, that sucked. It will tear up the skin on your knuckles and cuticles, it's tight, you cross your fingers and hope the zippers will hold and eventually the plastic window will crack. Otherwise when I wasn't doing anything that required getting stuff out of the back all the time it was ok. OEM heater is plenty. Hard top is nice for the rear defrost and wiper. Hold heats better, but the heater is really enough that it doesn't matter much, imo. Really I mostly just swapped to the hard top in the winter in a bid to make the soft top last longer. And I liked the look too, nice to mix it up.
I only got rid of the hardtop recently cause I bought a Gladiator for a year round daily... with a hard top.
::edit::
This was when I lived in OH, PA, and eventually MN. If storage is limited I wouldn't bother with a hardtop at all in Nashville, personally.
