I own both. I suspect the Notch is better in severe wind as it has smaller fabric panels to deal with blowing conditions. It is also not subseptible to how you pitch it in the wind as much as the Pro Trail. The Notch will also take some snow and is better to use if you are trying to blow the snow and / or wind with the fabric inner. The Notch also deals with condensation better by keeping you away from it with the double walled construction.
However, the Protrail is lighter, has more functional room inside for the bigger or taller folk, packs smaller and is less expensive.
On a side note, the trekking poles used to set up the Notch do not in any way impede ingress and egress as Jimmer suggests.
