Epson 5010 or Epson 6010?

I'm looking at buying either the Epson 5010 or 6010, not sure which one to buy?The price is about the same when adding a 4 year store warranty, extra lamp and 2 pair of 3d glass to the 5010. The 6010 comes with a 3 year warranty, is the 6010 worth buying and giving up the extra year of warranty I would get buying the 5010 with the 4 year store warranty and price being the same?

Thanks
