GOOD SNOW AT THE END OF MARCH - VERBIER, ST.MORITZ or INSBRUCK???

I´m planing a trip on march 25th.
Was thinking on hitting INSBRUCK, ST.MORITZ,VERBIER.
I haven't been in any of these places, so I ask more experient and local mates: what can you tell me about the snow quality?
Also, if you had to pick 2 or 3 three best places to go snowboarding in march 25th, where would you go???
Thanks.

I consider Verbier my home resort. It's quite snow-sure, as it has skiing aroung 3000 meters. But the quality of snow depends on so many factors that it's impossible to tell what it's going to be like on March 25. And this applies to every resort.
