If the Kazak Pro is anywhere near the quality of their Model 100, my vote goes there. Dare to be different, I say.
He's right, the Kazak Pro seems to be a quality choice for anyone who wants a "one and done" sharpening system, I don't see how anyone could point to you and say you're wrong. There are some differences that may be important to you that one has over the other and if you've used a sharpening system you know what they are and what bugs you when you're sharpening. My advice would be: DO YOUR HOMEWORK !!
I'm an investigator when it comes to making a big purchase and this is certainly one of those. There is a guy on youtube named Green Beetle and he's put together a great video describing the Kazak Pro and then goes over his TSPROF K03 system and the differences in the two. I would post a link to it but I'm new here and already been scolded for posting a pic using a host not approved so I'm skiddish.
Like I said before, once you start out with a sharpening system, you find things that bug you, for me, I CANT STAND for my blade to move while clamped in the system. I'm not talking about coming loose from the clamp, I'm talking about the clamp assembly moving or bending while I'm sharpening, I want it solid. I also don't want my system moving or sliding around while I'm working. If it does, then I find myself using my other hand to compensate for whatever is bugging me and I want that other hand freed up to do whatever while sharpening....... following stone, feeling the stone go over the tip, ect. If you watch the vid of him sharpening a knife on the Kazak, you'll see the clamp holding the knife moving down and back up from the pressure applied to the stone. May not bother some, may just be me.
As I said before, I have the Blitz 360 (2020 model) with all the bells and whistles you can add to it and I love it. The only modification I did to it was securing it to a piece of 1" thick piece of plywood for two reasons. One, to secure it to the board so it wouldn't move around because it's small and doesn't weigh much, it will move around when you go to "gettin busy" and two, while the system is secure to the board, I can place something under the board furtherest away from me so that the system leans the blade downward. Makes for better camera work for my vids but also allows me to see my edge better so I don't have to keep leaning up to getter a better look at my edge.
You're doing the right thing by getting on here asking and I'd definitely investigate before making a large payment on something that has a lot of "this pisses me off" things.
