Best? If you wanna get high-tech gore tex pro line stuff, you'll be facing 700$ for jacket and 500$ for pants. If price don't matter, go for it... But IMO, you don't need that for occasional trips to resorts. Those items are great if you use them a lot and hike (highest breathability for ascent and pack light cos room in backpack is limited).
Also gore tex is not a must... IDK the conditions in the locations you mentioned... try to estimate what you plan to ride,m. Are you the type who's out on the slopes also when it rains or if you call it a day when conditions suck? Are your trips in the high season when its cold? Then you don't need the same level of water resistance than if you ride early or late in the season when it's warm (e.g. cold snow will fall off your jacket, and your butt will rather freeze than melt the snow you sit on
while if you ride in spring slush conditions, the pants need to be highly water resistant as each time you sit down, you actually sit into water, and if you ride early in the season, it's probable that you face rain which requests a better jacket.)
For pure resort riding in prime season, mid quality already is sufficiant, especially for jackets. Go for shells and use layers so you can adjust your layers to conditions and also use the jacket for other outdoor activities.
General features I'd look for:
- Get something where you can zip or clip the powderskirt to the pants - a very useful feature which avoids that the jacket slips up then you fall (snow up your back) or bend down to close bindings (kidneys exposed to cold air can be uncomfy).
- Underarm vents and vents in pants are a must IMO. Even the best gore tex has its breathability limits when you run hot.
- Get at least one item in bright colors so you're easy to spot; e.g. all black is hardly visible in trees; don't get a white-white combination; you'd force crashes in flat light cos you are invisible then.
