I have seen the S/T Maxx described as a "hybrid AT/MT" and perhaps it is; if so I didn't give its "MT" nature enough credit.
The STT Pros are what most consider a "hybrid AT/MT", the ST Maxxs are a tried and true AT.
Besides that point, typically you sacrifice winter (ice/snow) performance when you choose MTs over normal ATs or ATWs, so you really have to compromise with what kind of performance you want out of your tires.
