I think you can also factor in what style of bike you prefer and the characteristics that brings - unless it doesn't bother you, which could equally be true
Personally I prefer the 26" wheel (which is why I have more than half a dozen of them!), quicker acceleration and more nimble feel, which suits the riding I like best (narrow, windy, climbing) - at high speed, downhill they don't feel so nice and take a bit more skill/bottle. Bigger wheels just don't do it for me - I don't even ride the 700c bike in the garage, my young daughters use it - but it provides more stability, which is useful a novice road rider
