Be very careful if you decide to "see both sides." I haven't professionally scored GMAT essays, but I've been a professional scorer for many other tests, and the scoring rubric is always the same on one point: if a student picks one side, in order to get a good score he need to provide a strong argument for that side. But if a student decides to "fence-sit," he has to provide a strong argument for BOTH sides in order to get the same score. By that, I mean that the (approximately) 5 paragraph length we looked for in an essay that had a single viewpoint was almost doubled in a fence-sitter essay. If you took your 5 paragraphs and split them between two viewpoints, we didn't see that as a 5; we saw it as 2 short essays cobbled together, and that would earn probably a 2 or a 3, depending on how it was done. If the GMAT rubric is similar (and I suspect it probably is) then no matter how well you see both sides, your reader has no choice but to hold you to a higher standard, one that might be difficult to meet with the time constraints of the test.
If you have trouble getting a long enough essay out of supporting a single side, try devoting a paragraph to mentioning what an opposing argument would be, and then disproving it. Then you get to use the alternate viewpoint but still stick to one perspective.
