There is no shortage of great brands, many listed above.
2 additional things I would consider,
Firstly the fit of garments, fit, cut, styling can vary a lot across brands, try before you buy, lots of outdoor shops, its not unusual to be between sizes across certain brands & find neither an ideal fit.
Secondly, the various technology, your spoilt for choice these days, various forms of gore-tex, e-vent, polotec neo Sheild for waterproofs, power stretch, power dry etc for a fleece base or mid layer, again look at them in the shops & try them on.
I would second a good pair of boots / gloves / hat at this time of year though!
