The GRE is easier on the math side because it is created for a wider range of Schools and fields of study: humanities, psychology, art, and so forth.
On the other hand, GMAT is SPECIFICALLY business school oriented which , of course, is more challenging.
Regarding the comparison that many people struggle with, scoring 600 on the GMAT and 330 on the GRE, we should analyze where they are weak on the GMAT and where they are strong on the GRE, as well as the types of questions they typically encounter.
I on a daily basis, see people struggle, the majority, even to reach 155/160

Good question.
Primarily, business schools still consider GMAT as the toughest test and a greater predictor of ones fit for success in business school.
GRE was introduced to expand the number of applicants and make it easier for applicants to get into business school. Also, I’ve seen many cases where people struggle to get over 600 on the gym and scored 330 on the GRE - the test test different things and the quantitative portion is frankly much easier.
Schools know this so they continue to maintain GMAT, at least for now as the bragging rights, simply because there are plenty of high GRE applicants, which means it’s not a great data point. It’s nice that you have a high score but that doesn’t carry as much weight if it was the GMAT score.
That’s the best explanation I can think of definitely not the definitive one or ultimate by any means. This is primarily basin observations so don’t feel obligated to take it as absolute.
