From my point of view the most important is throw and tacky topsheet like all chinese rubbers have low throw and Rakza Z EH is on revspin described as low throw when Rakza Z is known as high throw which is probably the most similar to Sieger
and this is where you got it wrong. you should not read to much into revspin ratings, because you don't know what other rubbers the people rating it know or play or what they are used to.
Rakza Z has a high throw, LAC does not have as high of a throw as Rakza Z, but still far from low in most shots. It is very similar with the Rakza Z Extra Hard which might not have the same high throw of the regular Rakza Z but probably even higher than LAC.
You have to remember that Rakza Z and Rakza Z Extra Hard share one topsheet (same registration number), so the only real difference is the sponge thereunder.
For very light impact/brushing strokes the throw will be identical between Rakza Z and Z EH.
Only when you go more into the power loop territory the extra hard version has more potential and can drive the ball more forwards which makes the throw a little lower, but still quite high.
Sieger PK is close to tenergy and hurricane 3 than yall think
I read here that LAC Has high throw which is always great when it is easier to grab the ball from downspin
I don't even know what we are talking about here ! so you are judging the throw of Rakza Z extra hard by reading revspin values and regarding LAC you also have no first hand experience and only go by what people write here ?
Sorry, but then there is no foundation for you to evaluate or give opinion about the rubbers or the comparision when you neither tried Rakza Z EH nor LAC.
If you want to get more insight into how some rubbers behave that are not widely played i recommend turning on translated subtitles for roning teams rubber reviews:
He does attest the Rakza Z Extra Hard a very high throw.
He has a review for the Rxton 9 which i did not watch yet online:
