I do rate the 305 over the 410, yes. And I know I'm not alone.
Among other things I like the buttons, the mapping and screen readability of the 305. I've never felt like "upgrading" to 405/410 and wouldn't even consider changing from the 305 if it wasn't for the fact that I accidentally broke open the casing on mine. I would buy another, but the profiteers are charging the same price range as the new 310XT - which looks like a true upgrade (longer battery life, fully waterproof).
Don't take my word for it though. Google the DC Rainmaker reviews for objective opinions.
