After having PtY, i have to say that I think Avery Maharaja (when in good condition) is actually a more impressive/unique beer. The problem with Maharaja is that because the volume of production is so much greater, it's quite possible to get old/oxidized bottles and kegs. With PtY, the demand so far outstrips supply, that nearly 100% of the pints of PtY consumed each year are in great condition.
The two beers are VERY different, but there aren't that many 11% IPAs out there.
