I've got the Camo version of the Cosmo Plus, after much umming and aahing…
No drop tail, but very very cosy and some nice features – stitched-in "gloves", lots of pockets, large reflective areas, nice fleeced collar. The single shoulder/arm pocket on the right does let a draft in thought!!
STW mag did a softshell grouptest (Last XMAS?) so you can find some good info there.
I do prefer the "purer" bike-specific technicality and features of my Endura Stealth – Dropped back, rubber "grippy" waistline, split pit-zips for use with backpack, zipped wrist on sleeves, large rear pocket etc but find I reach for the Cosmo far more often, and its quite often what I wear on a casual basis too, as it has a very comforatble fit.
