Which is better??

perspective not progresive 45

I would consider the 2004 flats (vs the 2003 linear perspective you mentioned) because some upgrades have been added to make them more durable. One is the blue laminate; the blue laminate has replaced the normal, center laminate and it's supposed to make the deck stronger. Also, all of the 2004 boards have a layer of polyurethane on the bottom to help them last longer.
