Help Me Decide: Kazak Pro (Black) vs TSProf Kadet Pro (Black) vs Hapstone R2 (Black) vs WE130 Pro Pack 2

Paging @wade7575 an 777 Edge 777 Edge to give a pros/cons comparison of the R2 vs the TsProf Kadet (or K03, if that's all you have) systems.

I own all 3 of those systems, and I also own most other systems on the market. The Hapstone R2 Standard (paired up with a fine tuning adapter, spring stoppers and a digital cube) is one of the best all-rounder systems available and will get your knives as sharp as any of the best guided sharpeners will do. It's also great value for the money with lots of affordable upgrades and accessories.

The TSProf K03 is one of the best systems money can buy, and almost everyone who has one loves it - but it's expensive and it takes up a lot of countertop space. Accessories & upgrades are also expensive.

I have both TSProf Kadet and Kadet Pro. I also have a Blitz 360 & Blitz Pro. They are nice but I am not a fan of the Kadet & Blitz type angle adjustment where the stone arm is "level" & used as your zero reference and the knife clamp assembly changes the angle. This ends up being VERY fiddly and you need to set and check the angle countless times to dial it in perfectly - every single time you change the angle. Every time you want change the angle slightly, your zero reference changes too and you have to go back and forth and back and forth until it's set again. I'm not going to dive deep into why this happens, but it has to do with the fact that the arc of angular adjustment only has a perfect circle center at a very specific distance from the angle adjustment point, and almost no knife will have the perfect blade length and clamp point to satisfy this design limitation.

Go to 4:45 mark in the KnifeKrazy vid above I posted. Is there a technical term for this tilting ? What is it called ?
I dont believe the TSPROF or Hapstone have this capability do they? So far I'm seeing only Kazak and Grid Viva or am I wrong ?
 
I think my TSProf k03 is the best sharpener all around, although the Hapstone is more versatile with the different modules (the M3 is great for my small knives) and their clamps are definitely the best imo. My problem with Hapstone is that the stone carrier, the threads stripped and it fell apart after a few months of use and I haven't been able to replace it. Otherwise it would see more use.

It's just a tilting feature, the whole system tilts if you want to reposition it for height / positioning angle for comfort. It's not a feature that I personally use or prefer in my Kazak or my Grid Viva at all. I always set them up perfectly level and sharpen from there.
 
Do any of the other besides the Kazak and Grid Viva have this tilting feature ?

Yes, some examples are:
The Edge Pro professional model, some Eastern European systems not well known in the US, some KakBritva models (like the Luch) has a tilting feature, etc.

The KakBritva Luch's tilting feature is a good way of tilting and one method that I really like because it's only the clamp unit that tilts in one plane, not the whole sharpener system. With the KakBritva Luch, this actually allows you to sharpen items like scissors without a dedicated scissors clamp.

An important note to realize with systems that can have all 3 planes offset (with a ball clamp unit like Edge Pro Professional and Grid Viva) is that it can negatively affect most digital angle cubes and your angles could be very far off because of incorrectly using your angle cube - even if the cube is zeroed. It's best to have the sharpening plane as level as possible (at least in the rolling axis plane) to be able to have a correct reading on your angle cube.
