The open style with a pour spout is the one I'd recommend. Mine, like StevieC's, is hexagonal....bought so long ago it was $7. I do like any deeper design.
Those closed ones (with the 4 slightly angled bottom panels which focus on a grille) are horrible because the draining oil splashes all over the place unless you crack the oil drain plug and let it exit slowly.
But, like they say, "If it works for you..."
My all time favorite application was an odd 2 gallon sized can of something which was tall. It stood and fit directly beneath my sister's Jeep's drain plug.
Perfect....until the thin metal developed pinholes.
I think it had been a thin decorative can used for holiday candies or some such.
