I don't know that I'd say it's better, but for most people it's not any worse. That's the truly important thing. Most people have already memorized the conversions they need, so it's already just as easy for them to use imperial as metric units. The only people that a switch to metric benefits are those who have to do lots of imperial-metric conversions, or kids who are currently in school and haven't learned the conversions yet. For everyone else, metric is actually a huge pain in the ass, because they have to re-learn to think in those units. So, for most people, the switch doesn't benefit them - but comes with a large drawback.
It's really not hard to see why the US isn't in a hurry to switch. And as one of the people for whom a switch to metric would be nuisance rather than benefit, I hope they never do (or at least, not in my lifetime).
