I agree with most. Carbide when ever they are available. With steel dies you must lube your cases or they may get stuck in the die. Lubing is not as big a pain as it used to be now that spray lubes are available, but it is an extra step, and then you are going to want to wipe the lube off again when you are all done.
For what it's worth, carbide dies are not available for cases that are not straight, such as 44-40. When I load 44-40 I first line up all my cases in loading blocks of 50. Then I spray each block with a very light coating of Hornady One Shot case lube. It dries to a tacky touch in about five minutes. When I am all done loading, I wipe all the finished rounds off while watching TV.
It does add a couple of extra steps to the process.
