I have a rather high end Latitude, (model lower than XPS 13), and every mac user that used the touchpad on it says it feels on par with the one on MBP.
It seems all the trackpads got worse when they went button-less to copy Apple.
Maybe the Latitudes have a better touchpad? I don't mind the Lenovo T-series touchpads and they look similar.
I also own MBP13 - and I prefer the keyboard on my Dell over it.
