So you want to compare MOSFETs. I think you will have to do this yourself by looking at the datasheets and looking at critical parameters like response time, maximum current, and source-drain resistance. I believe MOSFETs do not have a voltage drop like transistors do since the current does not pass a PN junction like it does in a BJT, but I could be wrong. That's how I would get started if I was making an LED cube.
