OP...50% is not worth paying for. go 30 or 35%, it's really just for looks.
My $0.02 - I would disagree. A car without tint here in the summer makes the AC work very hard mid-day when the sun is beating down. It will take longer to cool down - and I don't like to be in the direct sun without tint. With ceramic tint, the car starts out cooler (granted only just a bit), but cools off quicker in mid-day driving, and makes the sun angle a non-issue for me. Driving a loaner without tint (an A4 very similar to mine) made it very clear how much it was helping and convinced me of the benefit. F1 50% ceramic tint still rejects 49% of total solar energy, the 35% goes up 5% to 54%...
$500 sounds steep for ceramic - but even at that I'd say it's worth it. Had 35% before on my A4, and from the start I thought it was a bit too dark - both from looks and night visibility backing out of a lit garage (bright forward view made seeing out the sides/back more difficult). Visibility wasn't bad, but a few times I wished it was a bit lighter. This time I got 50% and it's just about right. With the all black interior & headliner it looks darker - the S4 might look a bit lighter than the S5 due to more glass area ...
I looked into the specs of Huper, Wincos, and F1 - after you reduce them to actual light transmitted vs. the quoted value (for instance - F1's 50% is actually 54% light transmitted) - they are all very close to the same heat rejection around 50% - as you go down toward 30% or 20% the Huper is a better performer in general - but only by a few percent...
Can't help with "carbon" - assume that would be like the "Comfort" F1 series -
http://www.formulaone.com/pdf/FormulaOneSpecSheet.pdf. If so, it's about a 15% difference in total solar rejection - 15% out of about 50% seems fairly significant to me, but that's a value decision for the OP to make
That's my opinion, so take it for what it's worth - which is very little.
