Get the triple. If you're a road racer, I'd say go double, but as a recreational rider, even a serious one, the triple will be well worth it.

I race occasionally and I'm no slouch on the climbs; I can take 20% inclines in a 12-23 cog (it's HARD) which would be very difficult for most non-racers to power up on. My other bike is a pure road bike with a triple, and even though I'm "strong enough" to not need a triple, I am very glad to have it - and Im definitely not "too strong" for it.

If you have any hills at all in your area, get the triple. If you're a Floridian with pure flatlands, ok, the double is ok, but even then, the triple is a good choice. Still, the reality is that there's not much of a difference between the compact & the triple, in price, performance, or weight. Those who moan that the triple doesn't "shift right" have poorly adjusted shifters - my Giant Defy runs a Sora/2200 (yup, LOWER than Sora) triple flawlessly. And I ride pretty hard on it - I ride with competitive roadies.

In my opinion, the "standard gearing" 12-25 is too aggressive for the vast majority of nonracing riders. I can hold 24mph on a 40k/1hr time trial flat course without drafting, and I feel that the standard double is aggressive even for me when there are any sort of hills.
