Oh I definitely think objectively it's a better game than the first one. Mainly because the level designs are really fantastic in here. But it's not a better game if you've played the first one just because unlike something new it's more of the same.
If someone hadn't played either, this sequel would definitely be the better choice. But, I might be in the minority here, the sequel just doesn't re-create that wonderful experience for people who've played through the original.
