I think that the GRE should be taken advantage of by people who struggle with the GMAT quant section. The GRE math section is a cakewalk in comparison
Honestly, I didn't find this to be the case, but perhaps that's just me. The GMAT may offer problems that are somewhat more complex, but it also allows test takers 25% more time to solve them. I mean, the material is exactly the same. I suppose if someone prefers the GRE's "Which value is bigger?" to the GMAT's "Which of these things do you need to solve the problem?" he/she might find the GRE more intuitive. But I wouldn't say either is inherently more difficult.
IMO, most MBA applicants should still prepare for the GMAT, unless they have a concrete reason otherwise, such as a plan to apply to a degree program that won't accept it.
