I would highly recommend test driving both (for an extended time if possible) before deciding, especially if you are unsure which one you would actually want.
My wife did briefly toy with the idea of the extended range Trophy (same price as XPower & has ~240PS vs the ~201PS of the normal Trophy) but ultimately she really wanted the Xpower variant specifically for its extra power.
The XPower drives like a firmer version of the Trophy and is generally rear power bias on <50% throttle (unless power is set to Sport) so day to day will feel basically the same as the Trophy. The fun really starts to happen in either full Sport mode or over 50% throttle in Normal mode... There is a notable audible change as both motors spin up and fire you down the road with reckless abandon.
Back to back the Xpower feels a little more planted when you start to throw it around but the difference isn't night and day. It is certainly no Fiesta ST in this regard but does feel quite similar to a Golf R or S3 (We have owned both a MK7 R and a 8V S3 for reference). Only thing missing is the engine note but for me at least I prefer the (relative) silence.
Efficiency wise the XPower is a little worse than the Trophy, hence the lower WLTP range total but in practice so far we are achieving over 4mile/kWh on our commutes. Thus the range of ~239 miles is pretty much bang on. At a guess the normal Trophy would likely net around 260-270 in the same conditions / commute profile.
Ultimately it just depends on what you want. Only thing I would say though is that you can match the "feel" of the normal Trophy in the Xpower, but you can't match the acceleration of the Xpower in the Trophy.
