It isn't the top of the top tier but it is definitely high up there:
Positives: No wasted mods, 10 Stam, 9 stats besides stamina. Has lmc which is important and has MR which is also a desired mod. Also its bone arms which are just cool. Obviously its a legendary with all resist slots filled.
Negatives: No eater and mana increase could be higher.
I'd estimate the value in the hundreds of millions.
