That's a tough one. I only have first hand experience with 6-7 roof prisms. My 2004 EO Ranger 8X32 & Leupold 12X50 roofs with Phase Coating have much better resolution and color fidelity than my 1986 Celestron 10X40 but the improvement may not be from PC alone. I purchased a 8X25 compact roof in 1990 for about $90 from LL Bean. it's made in Japan. Resolution is poor compared to my 2005 Burgess 8X25 Vireo bought on sale for $29. The Vireo has very good image considering the low price. Much Better than the $99 Brunton 8X25 Echo I ordered and returned. The Vireo is from China. Neither have PC.
I do not have a premium Euro Roof from the pre PC days to compared to.
I know having PC alone does not mean high quality image. My 2003 Pentax DCF MP 8X28(~$200) have PC but the worst internal reflection I've ever seen in a binocular. ( it was rated a Favorite and Best Buy by a Birding magazine, no less) An Eagle Optics Denali 10X42 has PC but resolution and image quality was worse than my Celestron 10X40 without PC. I returned it.
The new Oberwerk 12X50 Roof( $149) does not mention PC at all. Looks like a quality Roof Prism. I wish someone will order one and report back.

I see Oberwerk changed the FOV spec from 5.7 deg to 4.7.......
