From my personal experience, i feel that the ski companies, and companies that have made boots for a long time, have boots that last longer, and fit my foot better.
I have tried on a bunch of 32 boots and they were not at all as nearly as comfortable as Burton boots, K2 boots, or saloman boots. just my opinion though.
buy what ever boots fit your feet comfortably.
comfort and how stiff the boot is are pretty much the only things to consider when buying a boot.
