Topic says it all. For me that really does depend on which compounds I'm using. Plain leather, (pig or horse) is good for using as a steel basically and if it works for Salty, then I'm sold ,(also tested that out a few times
For liquid compounds like Boron or Chromium Oxide (pastes) Balsa is my choice for that as it adherers very good and stays flat unlike leathers which may curl.
Sprays: Now, I've tried them on balsa, and they work ok, but for me the really winner is split top leather. Personally speaking I think that the texture lets the spray last longer before having to add additional spray. Like I said personally speaking.
So what is your thoughts.

Ever tried newspaper with a lot of black ink? Leaves a rather aggressive edge.

Most overlooked strop material of all are the fine grit Shapton Pro and Shapton glass stones. The 16,000 grit is about 1 micron, and the 30,000 grit is .49 micron. Yes, they are expensive, but so is fussing with strops and sprays, which cost far more on a long term basis. No more need to buy sprays above .25 micron.

Stropping on the 16k glass can be really really good. Personally balsa and nano-cloth are my 2 favorite.

Try stropping on either of the Shapton 30K stones, which takes you down to 0.49 micron.
No need for balsa or nano cloth until you get to 0.25 micron, if you want to go that far so that you view a clean edge under a 40x to 200x microscope. I usually just strop on plain leather after the 30K, because I don't always want to drag out the microscope to look at the knife edge.

Hard rolled horse leather from Hand American and balsa are my favorites.

HA boron carbide on split leather - nice bitey edge.

Followed by stropping on genuine Cordovan horse hide, and your carbon will be screaming sharp.

Which reminds me. Mark, why don't you carry cordovan horse hide strops? L

I've been playing with making up my own laminates, similar to Micarta, but with a different epoxy, and I have been stropping on the handle scraps. I will be making up some to try with compounds and stuff, too. So far, the results have been a more refined edge that still has teeth to slice hanging paper towels cleanly. Also tried factory Micarta with a 100 grit belt finish on it and some 1 micron diamond spray. Works well, too!
