MEC collet system works fine, it does have to be lubed, PW sizer works like a rifle size die & needs to be kept clean too. No advantage one way or the other .
Reason I changed from 4 Mecs 20 16 & 10 600 ‘s ( 12 g was a grabber )was to save bench space. Two PW’s did the job. Other reason I like nice machinery & the PW machines are made like American machine tools were made 50 years ago. Smooth operating heavy presses .
Simplified my shotgunning now load 20 & 12 on one PW . Having said that loaded a lot of 16 on a MEC 600 with a short kit and it worked fine.
