Both are awesome, both have their pluses and minuses.  I like Colorado due to the consistent snow.  There's also tons of sunshine.  On the other hand, Tahoe has a lot of sunshine as well and when it snows, it nukes.  However, it seems you have more of a chance of a really pathetic snow year like this one.  But it's steeper, gnarlier, and can dump feet at a time.  Also, Colorado tends to stay colder more so you don't get the huge dumps followed by high temps that turns it to mashed potatos like what can happen at Tahoe.
