I'll add my 2cents...
IMO IPA's are better fresh as a standard rule. The less malty, fresher hopped IPA's (Lagunitas IPA, Torpedo, DFH 60min) are definitely better fresh because the majority of the flavor and character comes from their use of hops late in the boil and dry hopping. These beers are really well balanced and delicious, and I would not age one for 6months hoping to improve it because I think it would just kill the hop goodness and muddle the flavor.
An imperial IPA (or maltier IPA-DFH 90min, The maharaja, lots of others - DFH 120min is in a whole other category...barleywiipa) can go either way. The Maharaja (IMO one of the best IIPA's out there) is absolutely delicious fresh. I had a couple of bottles right at release and they were just bursting with fresh hop flavor and aroma...amazingly good. I had a couple more bottles at the end of may/early june (a few months after release) and it was still an amazing beer, still well balanced, but the malt was more pronounced giving a sweeter overall mouthfeel, etc... I still thought it was an amazing IIPA, just different. I think its about what style you prefer, and just what you are in the mood for. Sometimes a fresh, hoppy, aromatic IPA hits the spot, while at other times a good IPA with some more malty balance is just what I need.
Just some thoughts
I dont think there is a right or wrong answer, its all in the ingredients, and the balance and time-frame of the particular beer
