I ran a standard, then a compact for a few years, and have been riding a standard again for the last 12 months or so.
Pros of the standard is the nice gap between chain rings, and the 39 is useful in a fair amount of situations. Cons are that I spend a lot of time in the 53/21 53/19 53/17 sort of area. 39/27 will get you up anything but can be a bit of a grunt. And of course it looks like a proper bike.
Pros of the compact are that you can basically stay in the 50 all day, and a lot of the time you’ll be on a nice close ratio bit of the cassette with a better chainline if you are not generating monster power numbers. Cons are when you shift down to the 34 you feel like road runner and the bike stops unless you double or triple upshift. And they look rubbish.
That said, I’m changing back to a compact, mainly for the 50. I’m going to swap out the 34 for a 36 or 37 to get rid of that big drop in gear. That should cover all bases for a reasonably fit rider. You’ll not be spinning out 50-11.
