Ok, I have not had the time to read all the posts. Please see the photos below.
Blade is the same: Tibhar Stratus Power Wood (I told everyone, yes, I have 8 of them). Tested rubber:
Sanwei Target National (Black, not boosted)
Sanwei Target National (Red, boosted)
Rakza 7 red
Loki RXTON 1 black
Loki RXTON 3 Pink
Loki RXTON 3 Blue
Loki RXTON 5 black
Big Dipper black 40 degree (boosted)
Stiga Genesis (first generation black)
Fastarc G-1 red (really really old sheet)
I tested it mostly on my forehand side. Sorry, I cannot do a blind test like TT11 does. I don't have the time or energy. Plus, RXTON 3, I bought pink and blue for a reason. They look pretty! I bought them not intending to do a serious testing but since people asked, I provide the answer.
I like Sanwei Target National black unboosted the most. The loop is what I am familiar with (I use H3 neo boosted on my FH side). The loop is deep and spinning. Like I said before STN, right out of the package, without boosting, is like H3 neo boosted and not super tacky (you know, in the beginning H3 neo has super super sticky top sheet that makes the rubber sooooo slow; STN came out of the package sticky but the extra tackiness falls off right away so I like that about STN).
Second, I like Rakza 7. The loop is deep and cleared the net easily. The loop is a typical catapulty ESN rubber loop. Feels good and solid
Then Loki RXTON 3 Pink, Loki RXTON 3 Blue, Loki RXTON 5 black and Big Dipper black 40 degree (boosted) all feel about the same. Maybe RXTON 3 is slightly less bouncy than RXTON 5. When I do my forehand loop with all four rubbers, I just feel that I am barely crossing the ball over the net and my arc (and the amount of top spin I can generate) is not as good as I can execute the same shot with STN and with H3 neo boosted.
RXTON 1 black clearly softer sponge by far. But good beginner rubber. My backhand on RXTON 1 always goes into the net because I am used to using ESN rubber on my backhand side (EL-S, Rakza 7 soft, MX-S, T05 fx, etc. etc.)
STN red, boosted, posed a weird dilemma for me. It feels fine. The surface is tacky. But the sponge, after being boosted, feel a bit more solid, like a brick. I mean the booster is supposed to soften the sponge but in STN, it did the opposite. I preferred my STN black not boosted quite a bit, over STN red boosted.
Stiga genesis black first generation. Did not make much impression on me. Good arc. Nothing good, nothing bad. Not as catapulty as Rakza 7. Stiga genesis sasys it is made in china on the sponge! I think DHS makes that rubbre for Stiga.
Finally Fastarc G-1 red that is like 2 year old, I hated looping forehand with it. It gives a kind of hallow sound. I love it on the backhand. When I flipped it over and do the forehand shot, I hated it.
All my H3 neo has been pealed off and reattached to other inner carbon blades and 7-ply all wood blade so unfortunately, I cannot make a direct comparison.
I like RXTON series, especially 1. What I mean is, they are done well, not too tacky and good bounce. they can do well in internatonal markets! I think it is hard to sell Canadian and American customers on DHS or Friendship 729 products where the top sheet accumulates dusts like crazy and if you don't care for the rubber, the tackiness can go down very quickly. RXTON 1 is a perfect beginner's rubber but yet not too slow (When I ran university table tennis club, I used to buy premade Butterfly and Nimatsu Spinfighter blades from Paddle Palace; and those are real crap ). yeah two sheets of RXTON 1 slapped onto a cheap decent wooden bade from Loki will beat many of the premade recreational blades.
