Your decision could be based upon how you will be loading. If you use a 4-hole Lee Turrret, for example, you might as well fill the holes and do crimp in a separate step from seating. If lead bullet size is the issue, I wouldn't use Lee dies at all except for the powder-through expander. I use RCBS Cowboy dies in every caliber they offer. That is the only way I have found to coordinate the sizer yield and the expander size, both anticipating an extra thousandth. The crimp also then works at .001 larger.
I have some .357 lead for use in a tight gun, on which I chose not to ream the throats. For those I use my Lee die set mounted in a separate turret, normally reserved for jacketed bullets. Those .357 lead bullets (by Xtreme) are 158 gr, so I don't use them on 38, having no larger gun with tight throats. Those bullets are also harder than I use on 38. The Smith 36-1 (3" J-frame 38 Special) is tight but gets fed 125 gr bullets that are softer.
