All my Lee dies are three die sets just like RCBS and Dillon. I'm referring to pistol caliber die sets. What caliber are you looking at?
Anything worth doing is worth doing well.

The Lee Factory crimp die is nice to have if you have a gun with a match or tight chamber....
Basically it puts a nice crimp on any length case due to the collet sizing--it also sizes the entire case back to factory specs (no bulges).
only used for straight walled cases. I run them on the 45 and 10mm and 32 mag

While not required, crimping your cases does help to keep bullets seated in high recoil firearms and it helps to promote consistent ignition of the powder charges. I've used various dies to crimp cases and I've found that Lee dies are the easiest to use and they do a pretty good job.

Maybe I should get one of those for .357 Mag. For whatever reason, that round always gives me the most grief. I have to be extra careful on the crimp step, or I bulge the cases ever so slightly. In fact, the reason I have a cylinder sitting there in my sig pic, is to periodically "test fit" my rounds as I reload them.

HAHA I do the same thing. Its only the .357s and so far has only been the big ones ( 180gr).

The first DW I bought was a .357 SuperMag for silhouette back in the mid 1980's. It was an accurate gun. I noticed my crimps were not symmetrical. The cases weren't bulging, but no matter how I adjusted the crimp, they looked the same. You could see one side of the crimp was rolled into the cannelure more than the opposite side of the case, which barely looked crimped at all.
The brass had to be slightly loose in the seating die. The Sinclair catalog showed a Redding Profile Crimp die, which requires the crimp to be performed in a separate operation. This die is more precise, combining a taper crimp to the case and a more precise roll crimp at the same time.
My loads went from good, to superb with no other changes. Since then, I have a Profile Crimp die for all my revolver cartridges.

IHMSA, that sounds very much like the same problem I've had. Gonna have to get one of those dies.
If I have to take a fourth step in my reloading process, I think the headache relief will be worth it.
I have a few of my .375's that don't like to crimp straight (they jump crimp in my Seville), but I need to get a case trimmer to fix that...some of those case mouths are obviously not straight, just by eyeballing them.
