I generally ignore all the original oavs + Legend of Crimson Youth for Reasons, and mostly default to the manga instead of the anime (except a few cases where there's been bleed-in); Episode G and Next Dimension are likewise ehhnnn. LC I love but admittedly stop paying attention to after the wtf really starts to hit critical mass ;3

First season of Omega is yes, over on Alternate Universe Track #2865, but I haven't watched the second season yet because the new lead annoys the hell out of me. (I'm assured that I should get off my arse and soldier on because I'll enjoy the second half.)

Legend of Sanctuary should be hilarious wrongfun, booyah ~

The version of StS in my head (shared with a friend) takes more than a few more liberties of its own, but this many years on we're happy with the madness we've crufted together ;3~
