I have a 21 speed and rarely use the first gear on the front derailleur, but it's there if I need it. So MORE is not always better or even necessary but nice to have when you need them.
plus, I figure there's a fair amount of redundancy within those gears as well. not like I've ever sat down and done the math but out of twenty one gears, once you factor in all the duplicate combinations I wonder how many speeds you're actually left with.
again, only one way to find out. at $420 (globe work 1) it doesn't matter much either way really.
