I have an older Lyman universal (1980) it still is accurate but, I also have the lee quick trim that not only trims but deburrs and chamfer at the same. And I also use the Lee trimmer that I attach to a cordless drill.
The lyman,, set it up, trim a bunch then deburr and chamfer I have found that it works great for pistol (9mm, 357, 44 spl and mag)
The Lee quick trim,, accurate chamfers and deburrs at the same time. Con, the cases need to be lubed so that the o ring can get a hold of them without breaking, I use this system when I FL size my 7mm rm
The Lee hand system,, I put the shell holder in a cordless drill set to slow, put in a case, trim it, deburr and chamfer. I use this when I neck size my 7mm rm.
The fastest is the quick trim, then the Lee hand trimmer, then the Lyman.
They are all accurate and I think it is up to personal preferance
