I have not used eVent because of the weight, but am very pleased so far with a Rab Pulse, which will probably replace an older Patagonia Specter.
The vapor transmission on the Pulse is clearly better than the Specter when walking up and down hill for an hour or so in heavy rain in temps in the 55-60 degree range, with little or no clamminess on the inside. When cold enough to wear a fleece pullover underneath, remained totally dry.
But the DWR on the Pulse is not as good as that on the Specter. The water jumps off the Specter after being recently refreshed in the dryer, but only beads on the Pulse. Only time will tell how that affects performance when hiking in the rain all day; however, the Specter still worked fine in all day mountain hiking in the rain before refreshing the DWR, even though it was then not even beading well.
The length on the XL (US) Pulse is about 1.5" shorter than the Specter, but comes well below the waist and is around 30" below the back of the neck seam, and is adequate for me, as I wear Baggies or very water resistant softshell pants in the rain.
The Pulse is lighter than the Specter, and has the advantage of a full separating zip (not a pullover like the Specter).
