A waxed chain is so much better than an oiled chain. Cassette & chainring spotlessly clean, vs a chain lubed with oil, which is a magnet for dirt and debris.

After I am done riding, I quickly hose the bike down with a pressure washer and rub off moisture with a cloth and that's it. Since using waxed chains I've never ONCE had to remove road crap / leaves / mud from the cassette, it's permanently clean. When I'm riding I can feel the drivetrain working more slickly, a freshly waxed chain is like a brand new chain with the packed grease, but even smoother.

The only legitimate criticism of chain waxing is it's a minor pain in the ass to thoroughly clean the chain (using petroleum or whatever) before the first wax. After this all that's necessary is waxing 3 or 4 chains every few months. And you save money on replacing chains, cassettes, derailleur pulleys, chainring and so on because wax is a better lubricant.
