Audient iD44 and Motu Ultralite mk5 interfaces

[voloff]

I am looking to decide what suits me better with this two audio interfaces.
A comparative to know in what parts each of them are better than the other.
I don't care about what software or plugins that comes with each is better or the compatibility of the drivers, just the technical audio stuff.
If with the headphones one is better than the other, if preamps are better and why.
