Other than the physical dimensions of the case?

Looking at the data sheets, I don't see any other difference. Even the Theta-JC's are the same, although, intuitively, I would think the TO-264 package should have a lower thermal resistance.

So all you experts out there, is there any difference?

The MJW's are $0.51 cheaper per piece in small quantities, so if there's no real benefit to the MJL's, I'd rather save a little bit.

The JC-thermal resistance might be the same but the bigger case will have an advantage when it comes to case-sink theta, especially when using an insulator between.

Well...if that isn't a forehead-slapper. This was the benefit I suspected must be there, but wasn't thinking about it in the right way. I'm all straightened out now.

Thanks--
