I compared them recently for a project where I needed to make some PNGs smaller, and settled on pngng, which, in my informal testing, seemed to produce better results.

Make sure you haven't tested the 13-years-old pngquant 1.0 that is shipped with Debian stable and some other distros.

pngquant2 should clearly beat pngnq.

I tested v. 1.0-4.1 that comes with Ubuntu 12.04.1 (I think). Am I missing out?

Yes. 1.0 was written in the MS-DOS era, truncates quality to 15-bits, has buggy alpha and uses basic Median Cut algorithm from early 80s.

2.0 is by now a totally different program, with expanded and improved algorithms (with bits of machine learning) and uses 128 bits per pixel precision (SIMD+multicore optimized).
