They all work. Some have better features and lower cost too.
I find the Forster HOT-100 pictured above to be fine, it's certainly good enough for those of use who use factory rifles anyway.
It has a simple but functional calibrated head accurate to .001" per mark, shows in photo #1. As shown in photo #2, it has a slight angle on the cutter blade that makes it less likely to damage a case shoulder than a square cutter can.
Forster sells a wide range of neck reamers that can easily be inserted in the hole for the neck pilot. They will remove any interior roughness AND any "do-nuts" that may appear.
I don't care much for the plastic shell-holder but, fact is, it works fine. But I use a Lee case trimmer stud and holder chucked in a cordless screwdriver if I have a lot of necks to turn.
MidwayUSA sold me my HOT-100 Forster for something like $45 a few years ago. I MIGHT buy a K&M or Sinclair or Hart IF I had a $3,000 bench rifle to prep cases for. Otherwise, no.
