Ankle rotation? If you are referring to the bio-mechanical ankle brace on the Tech 10 inner bootie then you are incorrect - all Alpinestars MX boots from the Tech 3 up have an ankle brace built into the boot, the T10 is the exception where it is built into the inner bootie. The T8 inner bootie is purely for fit.
Both the T8 and T10 are more oriented towards serious racers, but the T10 actually has higher impact protection and also carries the weight lower in the boot. The T10 also provides more feel in comparison to the T8.
That said, all the brands you listed are good boots, basically anything designed and/or made in Italy are generally a cut above the rest. Note that most Italian brands are moving to manufacturing offshore, as is the case with most things these days.
