I really like having a windshirt. My approach to temperature management is lots of thin layers. I wear the windshirt over one or two wool layers and I can easily take it off and stuff it in a pocket if I get warm. You can't do that with a heavier jacket.

Don't have either of the ones you mention but I do have a Marmot Ion which is very similar to the GoLite Wisp. I find the hood a useful feature. I have another windshirt without a hood that is extremely light weight. My wife made it for me using Thru-Hiker's Liberty Ridge Shell kit. The momentum fabric is really light weight and windproof and quite water resistant. However my wife tells me it's a bit tough to sew on so it may not be a good beginner project.
