This guy on youtube doesn't seem to bend his knees a lot and doesn't go all the way down contrary to the exrx .gif of the guy demonstrating.

Is one or the other better technique/form than the other? I've been bending knees all the way, and dropping all the way but it feels kind of awkward for me. Any thought/opinions on either of these deadlift demos?

Also, is there any major difference(s) between regular deadlifts and romanian deadlifts? Thanks in advance guys.
