Advice on trois valley skiing

I have to ask the inevitable question - why specifically the Trois Valees? I've skied it from Courcheval 1850 and Val Thorens and it is good provided you can actually utilise the whole area. But when our kids were younger, we far preferred Italy because it was (a) much friendlier instruction (b) far cheaper (c) much less aggressive queuing and (d) they couldn't manage the whole TV area anyway. Don't get me wrong: now they're grown up they go to Val Thorens for its undoubted advantages. But when younger, Italy was our preference.
