I've ridden standard and compact on hills, flats, mountains. With 10+ cogs and so many different cassettes, you can find the right range with any crank. It's a matter of personal preference, imo. There are multiple compromises - so all you can do is prioritize. I grew up with standard cranks and still like that best for the shift pattern. For standard, one shift left is about 2-3 shifts right. I like this. With compact, one shift left about 3-4 shifts right. I don't like this since I almost always need to trim rear after shifting front - it's annoying. I like 53/39 with 12-30. You can do it with short cage 105/Ultegra. It works anywhere. OTOH, 50/34 with 12-27 has tighter spacing and some people find that more important. But, I'd rather keep 53/39 and swap to 12-27 or 12-25 to get tighter spacing instead if there isn't a lot of climbing.
