S30V/S35VN have been a standout for me. There is nothing I don't like about them. I can't honestly say that about the other steel flavors I've tried. 154cm is very good and I'm sure cpm154 is even better. SRKW's SR101 and S90V have been the biggest "wow" steels I've used but they're not really for me.
D2, A2, 01 - I personally prefer stainless.
1095, 5150, SR101 - puts off a stinky iron smell/taste cutting veggies. + I prefer stainless.
S90V, CPM-M4, Elmax - difficulty of sharpening not worth any extra edge retention.
Cts-xhp - I'm working on disliking it but haven't made up my mind yet. Gotta bang on it and sharpen it a few more times to be sure. So far I can't see how it is an upgrade from S30V.
I'm sure I've owned and used several more steel flavors, but like I said, S30V and S35VN have been the best do-all steels I've used. I've given much honest use and attempt to try other flavors, noting their strong points, but always come back to CRK and Strider's S30V/S35VN. As far as these two companies heat treat variances, in my use, the difference is practically unnoticeable and I would take the slight bump in toughness CRK gets out of a slightly softer target heat treat.
