It isn’t necessarily better... that just depends on what you’re looking at. Revolution is a different branch of MODx and is built up differently (although the usage remains similar).
Revolution has better caching possibilities, is faster and much more customizable then evolution.
However, Evolution has way more documentation and a lot more users who are active on the forums....
There’s a sticky in this forum about which one you should choose:

I’d advise you to get Revolution if you’re savvy enough to work it out on your own (with a lil’ help but not quite as much as for Evolution). If you’re not really interested in modifying the core or rather get step-by-step tutorials how things work, stick with Evolution for now. Migrating should be fairly in the future and once you know your way around with Evolution, the change is not that big.
