If you plan on riding in 20 - 40 degrees, rain or shine, then I would recommend a total windbloc type construction. This will provide adequate water repellence also - something you will need if you're in the rain any length of time. The disadvantage is the upper limit - which I've just sort of estimated at being somewhere around 40, give or take. Obviously a zippered front helps venting to some degree but, it will still have an earlier upper limit than the partial windbloc approach.

For fair weather riding, 32 degrees and above, I think the partial windbloc (chest and arms) is all you will need. And, stick a medium weight wool baselayer (ie., Ice breaker 220 - 300 g/m2 weight) under the softshell, and you will be good to 20 degrees. Merino wool is particularly comfortable to the point of feeling luxurious and, an effective insulator. Should you sweat some, it doesn't stick and it doesn't smell. A near perfect cycling baselayer. With a thin wool baselayer only, you can ride to probably 65 without much need to start stripping. So, the advantage of partial windbloc jacket is more venting/breathability thus a wider temperature range of applicability.

Either of the jackets you are looking at seem nicely thought out and made. Both Addidas and Patagonia are well known in the quality apparel circles (especially Patagonia).
