Research experience vs Graduate level coursework

<p>I'm ALMOST done with my undergraduate days, getting ready to sign up for classes. And I'm looking for a little guidance on the pros/cons of my two choices. </p>

<p>I'm an ecology student leaning towards the marine field. Currently I'm working in two labs on campus, one paid and one is giving me credit. I'm doing similar work in each lab.</p>

<p>For next quarter I'm looking into taking a graduate level class, and I don't really feel like my schedule would be very friendly if I did this and keep working in the lab for credit.</p>

<p>How do either of these options look to people (employers/eventual grad school?) on the outside?</p>
