I just recently picked up the jet 7's and have been using the anasazi vcs for a little while now. I really like the anasazi's a ton. they're great shoes and imo will climb most of the stuff the jet 7's will. the jet 7's on the other hand will really do much better on overhung stuff (cave stuff). I'd really try and gauge what you want your shoes to do for you and where you need them.
both are great at what they do, but from a shoe standpoint they're entirely different. jet 7's have the turned down toe, incredibly aggressive fit (much tighter in the toe box), while the anasazi's are flat (awesome for edging, especially bicycling/etc) and incredibly versatile.
some people complain about baggy heels in the ansazi's, if you try them on, I'd advise sizing them to fit your heel properly and understand that even with lined shoes the toe box gives and comforms quite a bit.
both are great shoes again, at the end of the day. determine what you want them for and understand what each shoe offers.
