Durability should be the same for both units. The X3 has a metal back plate and thus will pickup a little less interference while being close to a mobile phone. This happens to me when I keep my mobile inside my coat and the X1 in the outside pocket. Not a big deal and fixable with a thin sheet of copper under the plastic hood of the X1.
The X3's amplifier section is more powerful than the X1. This does not change the sound but gives you more headroom to drive inefficient headphones. The X1 will shatter your ears with most cans, so this is depending on your gear. And the output impedance is lower so if your headphones are susceptible against this, they may change the balance slightly with the X1. You can find the technical data at the FIIO site. To understand this measurements you can read the explanations here.
I did not write about sound quality for mids and highs because both units should sound identical with 99% of all hardware out there. With a given sensitivity of 112.0 dB @ 1V RMS and 50 Ohm impedance your HD598 should be an easy load for both DAPs.
