Default Metal cases for power mosfets

Instead of getting mosfets in plastic type cases (to-247ac), would it be any better to use metal cases, such as the TO-254? I went to a conference, and there were several companies using these metal cases:

Information on the packages

I will try to get some samples of these and see how the mosfets compare.

Their version of the IRFP240 is the IRFM240. They did not have the datasheet for it online, but they did have the sheet for the IRFM250:

International Rectifier also carries the IRFM240, their datasheet is at:

Information on Package

I found it very interesting that the transistor is isolated from the package, so no insulator is required.

It seems like it will cost a bit more then the IRFP240, but for applications such as the SOZ, not many are needed.

This could help cooling quite a bit.
