Most desirable sunder stats?

Apologies if this the wrong spot for this (didn't know if this would be a general forum thing or an appraisal request), but I got my first RotW sunder - yay!
Fire, of course. While the -10% enemy fire resist is perfect, I don't know what the most desirable stats are on a

Renewed Flame Rift (or other sunders in general). Magic find rolled near-perfect. Life rolled meh, but I assume life is better than mana? Is FRW better/worse than FHC, or +X to all attributes? And is magic or phys damage reduction preferred?

Short version: these things are incredibly variable, and I have no idea what to expect for offers if I put this up for trade. I've tried browsing here and traderie, and I see everything from a few

Jah to multiple 3/20/20. That's an insane range of value. What are the main differences there?

Like, somebody offered 18 Jah for this one, which is pretty similar to mine. 18

Jah is a fortune to me... but is that lowballing it?

Thoughts?
