I have my new setup on my 1050. I switched out the following Dillon dies; Lee Sizer, Hornady Seating, and LEE FCD dies. I loaded 1k and chamber checked 600. The new combo nearly eliminated the polish marks and line at the base of the brass. Out of 600 I had 4 fail chamber check, .00666 fail rate. 1 of the 4 had a burr on the rim that caused it to fail. 2 of 4 had a very prominent line at the base that caused them to fail.
I did initially notice slightly more effort operating the handle of the 1050 but not enough to count that as negative. I added more One Shot lube to the ziploc bag on the next batch and that reduced it further, still more then with Dillon dies but that is to be expected.
I also like the decapping pin on the Lee die better then the Dillon. Sometimes either due to the Dillon decapping pin being slightly bent or the round not that having perfect alignment. The Dillon pin would not clear the flash hole and I would have to stop operation to straighten the pin, realign brass or chunk the brass in question. I did not run into any of that with the Lee. I would also have primers not fully eject with the Dillon die, usually 2-4 per 100. The Lee had zero failures to eject. In general the Lee pin seems more robust, no more breaking the retaining clip on the Dillon. Not a big deal just a PIA, especially when you realized you have no more backups.
We will see how things go after 20k+ rounds but I am optimistic.
