I have already replied in the other post of yours with the same question. Still LSAT CR is tougher than GMAT and it will prepare you better for GMAT.

I used to recommend LSAT CR a little more often, but now my thinking is, have you REALLY exhausted GMAT CR to the point where it's too easy and you need to try LSAT CR?

I agree LSAT CR is harder which can be a great challenge for the GMAT CR rockstars of the world, but it can also be a little "too hard", so I wouldn't want you to waste your time on confusing LSAT CR questions that contain logic above and beyond what is required on the GMAT.

There are plenty of hard GMAT CR. I'd seek those out first before jumping to LSAT CR.
