Stoker's novel is pretty dry in many places. I read one of those illustrated classic books that was set up like our very own comics. It hit the high points without detracting from the overall story, actually making the damn thing more enjoyable.
King's
'Salems Lot is indeed far better. So is Brian Lumely's
Necroscope/Bloodworld series (IMHO the best vampire books EVER written, bar none),
Interview With The Vampire about the first eight or nine books in Laurell K. Hamilton's Anita Blake series and Bentley Little's (You knew he was going to be mentioned here.

)
The Summoning.
You want to read some good Vampire books? Read those I listed above.
Dracula is significant for it's importance to the genre, but isn't worth the time if you want something that reads smoothly and forges ahead with little lag. I don't think I'll be picking up the sequel.
