Most of you guys saying Moto Blur is crap don't know what you're talking about. It's possible you're confusing the old Moto Blur with the one on the Droid X, they are completely different.
The Droid X version of Moto Blur is an order of magnitude closer to vanilla Android than HTC Sense is. The Droid X version of Blur is pretty much just a few changed icons/buttons(in appearance only) and a set of widgets. Disable all of the widgets and your phone is nearly identical to vanilla Android with a very tiny amount of differences.
Blur is nowhere near the complete UI change that HTC Sense is. It doesn't force you to use different and oftentimes inferior versions of stuff that comes stock with Android. Examples being: Sense's built in text messaging program is inferior to the stock Android one(just scrolling up and down a conversation is laggy as heck), the stock calendar(trying to set the time for an appointment and I have to spin a wheel to enter a time in, you can't type it in) and media player are worse than vanilla Android's(Setting up playlists is way too cumbersome on HTC), the HTC Sense photo gallery is worse than stock Android's(Why did they take out Picasa Web Album Sync?), the HTC modified web browser is worse as well(You have to go through a ton of simple actions just to get the browser back to the home page and be able to exit the browser with the back button after a long period of browsing).
I had an Incredible for nearly a month before I moved over to the X. While there are a few things I miss from Sense, it is completely false to say Sense is just plain better, there are a LOT of things that Sense does worse.
