Dunno , I don't just do mud .. you asked for aggressive mud.
A lot depends if you want to drive elsewhere, or trailer something to a mudhole, like Frickley, or actually 'go' anywhere different. If you just do mud and want to blast straight through, then the above are good ..

If you go green laning or drive to Pay n plays or do anything other than straight lining mudholes then almost any Mud Terrain tyre can be 'good' .. depending on how you use it, again .. so much 'depends' on which is 'best'and no-one knows what you want them for, budget, wheel sizes etc etc .. according to you, you just wanted aggressive mud tyres .. doesn't say anything really ..
