I'm neither pro Sierra nor LucasArt in adventure games.
I like games from both companies.
My picks from LA: Maniac Mansion, Day of the Tentacle and Sam & Max: Hit the road,
and from Sierra: Gabriel Knight series, Larry series

It all depends on which game are you talking about, to me Gabriel Knight 1 beats any other game storywise, both in depth and development.
