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.

Its the same transistor (die) in a different package. It has less metal plate to heat sink transfer. This means that the MJL has better cooling.

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.
I thought the W versions were a higher rated version???? the MPSA42/92 vs the MPSW 42/92 has the W version at twice the dissipation. i thought....
