Like what
@Junomano has stated, it is tiresome because you see it in most isekai stories. For me I rather it be someone that earned it & worked hard for it. Perfect example would be
The Exiled Heavy Knight Knows How to Game the System (sadly it got purged), the protagonist knows what build is the best & what to look for. Even if he has the components for it, there is still risk of him dying since the equipment & skills can't carry to OP status. His real strength is he a lot of macro knowledge & micro knowledge that allows him to do take fights that a normal person couldn't do. Just being god level of power from the get go is does not make a very interesting story when it has been done to death. Nothing wrong for people liking that stuff but I've seen enough of it when you read as much stories as I have. Hope this helps provide better context.
