I've used both jake and strutters.  The only strutter I've used is ones I attach a real tail and real wings.  There's nothing like using the real thing!  The wind blowing through feathers looks a lot different than if blowing against plastic/rubber!  I can practically see tom's eye's pop when they see the real strutter tail fanned out!  I have often had success using just a strutter....sometimes just hens, and sometimes a little of everything.  I also use an open blind and can all of a sudden pull out a strutter to get a tom's attention.  When he was watching a couple hens and all of a sudden a fanning tom shows up....you can imagine how that irritates the tom!
