veatch is correct on the different body sizes.
I, personally, like the slightly bigger body on the Newport, over an LP.
Another thing to consider, with a Newport, is its weight.
The spruce topped Newport is nice and light although, I can't comment on a maple topped one as I've never had the chance to play one, yet...
The Newport is much lighter than almost any LP and it's also a bit lighter than any 335 I've owned, thus, making it easy on one's back when played for extended sessions.
