To be honest, I would expect laminate to hold up better than just about anything else. That said, you probably don't need as much durability as you think. Most cocktail tables are made with cheap plywood or MDF. So it's not like you need to skin the cab with 18-gauge sheetmetal and paint it with Por15, for example.
While I'm impressed with the weight of MDF, I'm not very impressed with it's strength or durability. I'd probably use plywood or MDO for this... but then again, that's what I tend to use for everything
