I have both, depends on what you're using them for. If you travel with them, the 2.5's are smaller and fit in certain coolers better, plus a 5 gallon batch fills two of them nicely.

For me, I would buy the cheaper of the two.

I've picked 2 1/2........... that way I can split a five gallon batch into one keg, and one case of bottles...

10 dollar difference between the two so money isnt an issue.

3 gallon one will carb 2.5 gallons of beer faster.

more headspace for co2 ? or more surface area for the co2 to interact with the beer

Head space has nothing to do with it. It's only surface area that matters and they are the same for 2-1/2 or 3 gallon kegs. The only time head space would effect it is if you disconnected the gas. Otherwise there is a constant pressure of CO2 on the given surface area.

The gas is pressing down on the beer. That pressure is measured in pounds per square inch. More gas volume = more square inches = more pressure on the beer forcing gas into solution faster.

Try it.
