Compared to for example Focusrite's Saphire Pro 10/10, which I had on test for a week when making the new purchase desicion, the build quality alone of the Motu isn't that much better, but the drivers are!
The Motu driver hasn't failed me once now (only been in use for a couple of months, though) and can take more strain on a 128 sample buffer. I find that the only allowable buffer size for live playing (for drum pads, keyboard software synths etc.).
Go for a quality interface and you'll actually save money on the long run and make more music
