The pinnacle of trimmers are the Giroud, Henderson and RCBS Matchmaster (which was developed with Henderson).
The new Hornady 3 in 1 is a blatant copy of the Henderson. Probably excellent, but my money went to the RCBS matchmaster.
The Lyman case trim xpress is a poor man's Giroud. Excellent little case trimmer. Strong motor, zero plastic and it is super consistent. L3i makes 3-way heads for it, which I highly recommend. But I recommend 3-way cutters regardless of what brand or model, they're worth every penny.
I briefly used the trimmer on my FA prep center and didn't like it. The plastic bushings didn't fit some cartridges well and I couldn't get consistent trimmer lengths. The Xpress was 10x more consistent, way easier to set up and adjust and I could buy 3-way heads for it. This new FA trimmer could be much improved, but I haven't used one.
I've only owned one lathe trimmer - the RCBS trim pro 2. Used it for 3 years and absolutely hated it. Trim lengths were never consistent, the universal case holder sucked, and tweaking trim lengths required an Allen key. Would have been better if they used their collets instead of that universal contraption. The Xpress beats the brakes off that POS.
