i still use PP2014.

i've no real interest in Superfly. and my husband had both P11 & P12, and we did a little testing...

turns out, for me, the Firefly engine results in P2014 look best to my eyes when compared to FF in subsequent versions...

so i'll say i use what i use due to personal preference visually speaking...

or i suppose that i could also say i just love retro things ;)
