[Autodidact]

I've read through tons of threads on here about plugins and mods for improving the kobo experience, but most haven't been updated or replied to in 3-10 years. Furthermore, I've heard that the built-in kobo reader has gotten better over the years, as have other built-in features. I've just purchased a Kobo Libra H2O so I am wondering if there are any tried-and-true plugins/mods that improve the experience of owning a kobo with respect to reading experience and book organization (not interested in playing chess or anything like that).

I'm sure there are lots of shiny new plugins and mods that I will explore in due time, but for the time being I am searching for timeless things that have nearly consensus endorsement by experienced kobo users (things that have a 50/50, love/hate split would also be interesting to hear about).

The short list of candidates I've come across:

Kobo touch extended driver?
Kobo Utilities?
DeDRM/Obok (no question)
KoReader?

Are the first two no-brainers, or are people divided on them? I already know people are divided on KoReader and other alternative readers, but generally speaking are they as popular as they used to be? And if so is that due to reading experience and book organization reasons or just chess-like reasons? And are there any other basics I should know about?

Thanks in advance. Like I said, I know it's been discussed many times but there's seems to be a need for a more up-to-date discussion on this.
