Not at all, you can't buy maxed red rings, wedding dresses, etc. with simple dts or pds, only with the best of RNG can one drop which would be far worse odds than something like a PGF or STA even. As for the Offensive Upgrade assuming you look at that with pure stats alone 99pds=30% at Gallon's Shop, while 15nycs=30%, making each NYC at worst equal 6.6pds only with more utility.
The hunt for them was probably the fastest 6 pds you could make, not to mention if you don't like what this year has to offer you can save them for next year and have a head start.
The value and utility is AMAZING!
