I'm inclined to agree with part of this, but not Sea of Red and Gigantic. IMO they are far from Rick's best work, they do not top X-Force by a long shot.
All a matter of opinion. Given that I cannot stomach pretty much any of Marvel's X-franchise, and I liked both Sea of Red & Gigantic, I feel differently.
I tried Remender's X-force on 2 separate occasions. Didn't do anything for me either time.
