Various: S30V, 20CV, CTS BD1N, D2, and VG Max Damascus (Shun Chef Knives). Thank you.
Let me start by saying I have no experience with water stones. So I cannot give any commentary on them and nothing I'm going to say is in anyway a comparison to them.
Then let's say that no equipment on the planet will substitute for understanding the fundamentals of sharpening. See the stickies here, abuse the search function, and research YouTube.
Next is understanding the steels and for that, the zknives steel chart site or app are excellent:

Let me also say, I am always a fan of 8" stones.
You have a mix of steels and in my opinion, you don't have a one-size-fits-all solution. One key element to look for is vanadium (V). At 4% and above, diamonds are preferred.
In general, sub-4% vanadium carbide steels can be sharpened on silicon and aluminum oxide stones. This your BD1N, D2, and VG Max. BD1N is really nice to sharpen. So here, at a minimum I recommend a Norton Crystolon JB8. But my preferred approach is a Norton Crystolon course stone, Norton Fine India, and a soft Arkansas for final honing. Paired with a leather strop for de-burring and maintenance. You can skip the Arkansas, I just really like them.
For the higher vanadium stuff, then I recommend diamonds in 300 grit and 600 or higher grit. DMT is excellent but the Ultra Sharp line is a good value as well. One or two diamond stropping compounds on some paint sticks.
A universal stone holder is a must in my opinion as is a red Sharpie for marking the bevel.
What as your experience been with Arkansas Stone? Do you prefer using the oil w stone or water? Thank you for the information.
Oil. Always, always oil. I've used Arkansas stones for around forty years. Honing oil is highly refined mineral oil and is the best to use, this goes for the Norton stones too, but you can get away with laxative grade mineral oil in the pharmacy section of your grocery store.
Spend time understanding what you're doing when sharpening and what you're trying to make happen and it will help you decide what you want. Hope that helps.
