Sean simple answer is it depends. What is your goal, and how do people want to play. If it's for fun, with an extended pool of cards, the deck builder is ok, as for a small outlay, you get a mix of cards. However now the core set has changed to 2012, and therefore if you are playing Standard (or type 2) then only cards from the current base set, and anything from the current expansion block and the previous expansion block are allowed. so some of the cards you will find in the deck builders set will not be type 2 legal.
I am getting back into it, by going to TWG limited tournaments. You pay for a few boosters, and get some cards to build a deck with, and everyone has this limited pool. Wizards are currently producing some Event decks. These are themed decks, with a mix of Standard legal cards, and a sideboard, which if you fancied playing a type 2 standard tournament, would get you in. They are not by any means optimal, but can give you a place to start tinkering and tuning a deck from.
