If your doing down the Bowden extruder route1.75mm is the only real option,

I was always told/heard 1.75mm was preferable on the bowden as it was lighter, didn't have as much spring and less pressure needed.Quote

Why? The Ultimaker is Bowden and uses 3mm filament, and has arguably some of the best prints of any RepRap-based printer, with exception to individual machines of course. The Tantillus uses 3mm as well. I have built a 3mm Bowden machine with a 300mm x 300mm build area, and it works just fine. 1.75mm filament allows for a more compact extruder, but that isn't really an advantage for a Bowden printer unless the entire printer is very compact and space is at a premium.
In the end it really is just personal preference. I have been printing for years, since back when 3mm was the only (inexpensive) filament available, and haven't seen any real incentive to change to 1.75mm. I really don't think one is better than the other in all respects. Flexible filaments are much more usable in 3mm diameter, but stiffer filaments are maybe a bit easier to deal with in 1.75mm diameter. Flexible filaments in either diameter will not work well (if at all) in a Bowden setup.
