Practically, I prefer space heating in the winter to spot heating (from solar heat gain from the windows) in the summer... So, I would prefer to block radiant heat which is a point source and difficult to combat in summer, and difficult to distribute in winter, and in doing so, put up with using a little more heating in the winter and less cooling in summer... The cost would be a small difference (if at all), so comfort would be my preference.

I had a quote that was just under 20K which included new frames (obviously). As this is out of our price range I had considered looking at Low E glass, however after reading about the thermal shock and other downsides as mentioned previously in the other replies, I'm thinking maybe not. However it does make me wonder if tinting windows would give the benefits of Low E glass without the side-effects. It was suggested I looked at Vortex IR70 Optical Clear by UltraGard as a tint we could put on our windows for a fraction of the cost (about 4K). Apparently it helps keep warmth in in the winter and heat out in the summer. So is tinting current windows as good as Low E Glass without their risk of thermal shock but with all the benefits, or is it the modern magic beans? Thanks in advance for your help.

Berek, are you saying the Tint is only recommended for double glazing or Low E glass? Thanks.
