A wide, fast-rolling tire like the 700x32 Vittoria Voyager Hyper might increase comfort noticeably while not being terribly slower than a 700x25 training tire...
Don't miss the point. The factors that a lot of recreational cyclists are chasing are quite similar to those of the professional, albeit far less of a necessity. For most recreational cyclists however, they are ok to trade off some speed or ease of climbing for ride comfort. Plenty are not. The point was made and it wasn't correct.
Also consider the fact that any frame that can accomodate 32mm tyres will be a far more comfortable frame to ride in general than one that is focussed around 23-25mm tyres. Frame geometry and then frame material and tube profiles means a whole lot more to comfort than some pieces of rubber.
Also don't discount tyre pressure. 32s can easily feel as uncomfortable as 25s at the right(wrong) pressure.
The conundrum isn't just black and white. There are far too many variables for any blanket staements to be made on discussions like these, which makes them so futile and polarising........ but good entertainment if you have nothing better to do
