I was wondering why some people decide to "upgrade" from 27 to 700? I would think a bigger wheel would cover more ground? What do you prefere?

I have one bike with 27x1. I wouldn't change it because the frame and brake reach works well now.

All my other road bikes are 700c and will probably stay that way also, and thinking of 650c for a better fit for my wife. TT/Tri trending toward 650c for performance.

The 27 would be good for touring as you're eluding to.

The main argument seems to be "you can't find any good tires in 27", but I just got a pair of Vittorias for the wheels I'm building for an old Carlton.

Tires are still available for 27" wheels for now, though the selection is limited.

Another reason some switch from 27" to 700c is to make additional room for fenders and fat tires. To make that work though, you need to be able to adjust the brake pads down 4mm. Usually not a problem.

Performance wise, I don't see any difference between 27" and 700c on bikes that I've had both size wheels on.

Manny of the old british bike frame and brakes were designed for 27" and 700s.They were built this way as to be able to use "sprints" or sew-up rims which are 700 size.So using a 700 clincher is not a problem with these bikes.I find wolber model 58s in 700s to look very pleasing.I do think a very thin modern 700 in these frames looks a bit strange.---sam

Also, if you want those really lightweight wheels with exotic spokes that can be counted on the fingers of both hands, 700 is your only option. I'm not aware, at least, of any 27" rims for fewer than 32 spokes.

Come to think of it, I think the limited availability of rims is more of an issue than tire selection.
