compact crank choice
As far as compact cranks are concerned which is the better choice. 50/36 with a 12-27 cassette or 50/34with a 12-25 cassette? Opinions appreciated.

I had both, and I personally prefer the 50/36 with a 12-27 cassette. I just hated the huge drop when I dropped from the 50 to the 34.

Calculate the gear inches at Sheldon Brown's site, and you'll see how different (or not) the ranges are.
Then take into consideration your fitness level and the terrain you ride, and make a decision.
Others' opinions based on the lack of information in your original post are nothing more than idle chatter.

I have a 52/34 with a 12/26 in back, the 34 only gets used on big climbs. The only down side I have noticed is the huge difference between the 52 and 34 makes more chain rub combos on the small ring but shifting remains great and dont drop chains

I now have compact cranks on all of my street bike save one and they're all 12/27 - 50/34 and I've been bettering my records all over the place.
Of course I live in the San Francisco bay area and there is a lot of climbing around here so you have to take that into account.
I generally don't use the lowest two gears but there've been occasions when low gear was REALLY welcome. Like two weekends ago when I went up some of the nastier climbs on the Marin peninsula. One was a 10 mile climb with a false flat in the middle and a lot of 12%+ sections. In about 70 miles we climbed 8000 feet or so.
So I love the lower gears. BTW, on the Foxy Fall today (almost all flat) I averaged 17.4 mph with that same gear so it isn't as if you're being limited or anything.

Here's a link to the article about next years Compact cranks from Shimano.
