Well, I guess I came to the same conclusion everyone else does. There's nothing like H3.
I searched far and wide, high and low, cheap and expensive, tried a bunch of options from almost all of the Chinese manufacturers and some of the other ones and I've come to the conclusion that while Battle 2 and Battle 3 are solid and the better versions of Target are usable, I'd much rather just pay a little bit more for H3. This is after having tried "high-end" rubbers like Dignics as well.
What was especially surprising is that both a 42A National blue sponge (Unboosted!) I've tried and my own 41A Provincial blue sponge feel very easy to hit through and they will crack on anything that's not a slow brushed shot. I'm a beginner by all accounts so this shouldn't be possible according to the internet, but that's what I've found. It doesn't feel hard to hit through at all.
Surprisingly it works on the backhand as well. Definitely not ideal sponge hardness, but it wasn't that far off my objectively much softer backhand rubber. I can understand how some players will use 37-39A on the backhand.
Part of it is probably that I'm familiar with the orange sponge and it's a psychological thing, but that's my 0.02. It will be interesting to see if these views change as my play level improves years down the line.
PS: Hardness consistency on the Provincial is incredible. Mine was 51.5 O topsheet +-0.10 and 56.0 sponge +-0.10. I've only ever seen that kind of precision on Butterfly and Nittaku sheets. None of the other Chinese manufacturers produce anything as precise, the best they can do is +-0.25, but +-1.00 is not atypical, Yinhe sponges are mostly like that.
For reference Commercial H3 Neo 40A is 49.5 +-0.50 topsheet and 48.5 +-0.50 sponge.

In terms of actually playing, there's not that much to report. Slow and steady improvement. It'll probably still take me a while to get to my old peak playing level. 10~ hours a week isn't enough to really improve quickly, and my body can't manage the kind of hours I did anymore anyway. I used to play for about 25 a week.
I'd love to post some footage but there's privacy concerns so I may have to not do that. I might post some video of just myself serving some time for fun. Highest division amateur players, state players and ex-national players cannot return my serves adequately and often make outright mistakes on them so it would be very entertaining at the very least. No I don't hide them.
