So, which one do people think is A) easier and B) prefered by biz schools? Or are they about the same? Gotta decide soon which one to study for and take.

Go with the GMAT. The rumor is that the GRE is easier, but I think the GRE is still kind of an unknown for most business schools - even those that accept the scores. I think most unofficially still prefer the GMAT. Good luck.

GMAT most likely.

The use of the GRE in MBA admissions is relatively recent, and only a fraction of the programs accept it, while the majority of programs take GMAT. Maybe in a few years this will change, with the GRE being accepted in more programs, but for now it's only a niche.

But if you are set on a school that only takes the GRE, then that's a different story. Look at the individual programs you want to apply to. A few programs that take the GRE include (they might also take the GMAT instead, so check that out):

The California State University (CSU) system: Bakersfield, Chico, etc.
Stanford
Wesleyan
Purdue's part-time program
Boston College
Yale

Yeah, I'll just take the GMAT.

I kind of doubt any good schools would take GRE only.

I'm considering taking the GRE instead of the GMAT, and I found this thread but it looks like it's a few years old...

Has there been any change in business schools embracing the GRE? I see that a lot of the top business schools are now taking the GRE - ones that I'm considering are Stanford, MIT - Sloan, Harvard, and New York University - Stern.

Has anybody on this board heard of a candidate who was accepted after taking the GRE?

Accepting the GRE is a way of schools getting access to two pools of candidates: those looking at other graduate degrees; and those who are worried about the quant element in the GMAT. Applicants need to be be careful about what they are signalling.
