About the 6 Science Adventure Visual Novels.

I've been looking to try these six VNs in Japanese. For reference I read and I'm able to read the サクラ大戦 series, マブラブ, Clamnad and was able to tackle the 真・女神転生 series as well as Persona and Atelier series and the Blue Reflection games, although those are an RPG and not a VN. I've also read the 学園ヘヴン series. At my level, reading and playing all these is fine. I have to look up a word in a dictionary here in there but I'm fine. I have bought and tried VNs that were too difficult for me in the past and had to stop and will have to try again in the future when my Japanese level is higher (these were 東京陰陽 and 大正メビウスライン)

My impression of the 6 Science Adventure VNs is that they're harder than anything I have played/read so far. Would you say these are difficult. And how would you rank all 6 of them in a Japanese immersion easy to hard tier list? Do you think I've be ready to tackle them considering I'm able to read the games/VNs mentioned above?

Since each deal with different topics, e.g. Chaos Head is about an MC that has hallucinations and can't distinguish between fantasy and reality, so psychological horror. Stein's Gate is about time travel and casualty, Anonymous Code is about hacking, etc, I got the impression that some would be harder or easier than others.
