I've got exactly both. My townie is a 22lb felt brougham, and my track race bike is a cannondale Alu bike that's about 17lbs. They feel about the same on hills, but we don't have anything very sustained, mostly just punchy short stuff, so weight isn't as big a factor. I'm also 180lbs, so the % of my weight may be much smaller than others.
Your mileage may vary.
