I'd have to go with both of you. That 54 print is glossy and thick and the tones are great, although it's never really very sharp. I've made plenty of those that have ended up in frames and under glass. They're great.
Oh the other hand, those 55 negatives are great too. VERY sharp, great contrast range. To me it seems like they're at least as sharp as TMX but with the range of HP5 or Bergger.
I find myself buying and using both.
