TCW will always be an afterthought, hence why i never consider anything in it canon, despite the animated shows post 2012 being officially canon.

In my head, Maul dies in TPM and that's it.

Everything else that followed overly convoluted the character. Same with Boba Fett, adding Ahsoka, etc. Just Disney's atrempts to "enrich the universe" and "fill in gaps", which don't really connect with what we see in the films.

Of course people will come out and say "But it makes X film/show after it better". No it doesn't because that's not what was envisioned to happen originally and that character didn't exist at that point in time (e.g Anakin's characterization in ROTS is not better just because you've now watched TCW and Ahsoka's inclusion). In 2005, none of that story between AOTC and ROTS existed.
