I really like this armour but I think saying it's cut down jag and sticking a big price tag on it is not correct.
Let's compare it to phantom:
Both have the same c/s/i but phant edges it due to 25v20 impact, very few mobs do just c/s and against all others phant is equal or has the edge.
All acid mob atm also do impact (except for pure acid) so the 8 v 1 acid is balanced a lot due to 20 v 25 impact. CRA has a slight edge but less than the edge phant has in c/s/i
Cold is equal but chompers do imp/cold which gives phant a 5point edge on those.
For bots it's 22 v 21 in favour of CRA but the higher burn of phant helps more with some mobs so this is at least equal, and arguably slight edge to phant.
Elec mobs, phant wins hands down as CRA has no elec protection
So if we ignore durability and weight then I think phant wins fairly easily.
