Victini still has a Choice Band set as an analysis, and as long as a set has an analysis on site, it'll probably be in that section regardless if it's outclassed by another set. Ideally I'll link this compendium with the OU Sets VR rather than the OU VR to help distinguish between good sets (Z-Tini in B-) from niche sets (Band Tini in C-). Pex has an Infestation mention in its primary set, while Tapu Fini also has a Whirlpool mention in its main set, so I'll also definitely be leaving those in for now.
The rest of the sets were/are in the compendium because of their mentions in OO. If a set gets a strong OO mention, they've generally been included in this project. However, when this project is linked up with the Sets VR, they should be relegated to the niche sections.
Good OO sets include things like Suicide Lead Scolipede. While its primary niche is SD water z, you can still use it as a decent dual spikes lead that isn't completely outclassed by focus sash gren, because it allows you to use an offensive Greninja as a teammate. Suicide Lead Scolipede also gets a strong OO mention in its analysis.
Examples of bad OO sets are CB Buzzwole and Scarf/Specs Victini that tend to get talked about negatively in their own analyses and are extremely niche on Pokemon that are already have only a very limited niche in OU. Removing those.
