It's just anecdotal silliness, but a friend of mine and I have been comparing power numbers for a year or so. IIRC he weighs in the region of 85kg and has an FTP of around 320w, I weigh 70kg and last year I had an FTP in the 280-290 region (lower now). Predictably he blows me away in TTs, he's about 2 minutes faster over a 10mile TT and his 25mile PB is about 5minutes faster than mine (his CdA is also better).
Last week we rode up Oxenhope Moor side by side. His average power was 271w mine was a very comfortable 208w. It really is striking when you realise how much difference weight makes when you are going up hill!
It depends what your goals are.
