I think they're asking if they should trust those list of "best isekais" coz how one could have read all of those 200 "best".
It's like she's asking if she should trust the food reviews of a food blogger that tells everyone that every place they have eaten at was "the best place to eat at." Like, wouldn't there be the worst , too? Or wouldn't you find this certain place greater than the other? Idk if my analogy worked.
Aaah no I get it now thanks for explaining. Also in my opinion I think the best way to know if the list is trustworthy or not is to go through the account of the person who posted that list. If that person has read over 1000 manga/manhwa combined (not just yaoi yk, like I've seen people with 600 already read but they're just yaoi and shounen ai). For example the lists of Being You are pretty good and trustworthy since I've found a lot of good isekais from there
You should look into it if the list is trustworthy..
But honestly 200 manhwa is actually easy to read in a year or more. I've been reading since I was 13 novels then around I was 15 I've been reading manga/manhwas. And it's been maybe 6-7 years since I've been reading. I've almost have read atleast around 2,000+ including novels, manga, manhwa in it. (How do I know? I have saved my chrome bookmarks of everything I've read, also put them on folders)

Oh btw if you want to, you can try checking my list, it's around 300.. The last bit (end part pg 32) have some comments and spoilers (it's during 2021) and after a while I got lazy with putting my reviews on the new-er ones
cause how can one fr have read almost 200 isekai manwhas and label them the BEST???
