I didn't say WarioWare was subpar. I do think Get It Together! was interesting for its unique approach, but I didn't vibe with the minigames, presentation, or the characterization of the cast. Wario Ware Move It felt bland in comparison, more of what's expected. Neither of them were as good as Gold, and I'm burnt out on the series.
Regarding Paper Mario, the preference of which titles are better is completely subjective, I agree. However, if we use review scores to gauge the reception of the market, which I'd argue is one of the most common metrics used today, the quality of the titles have been steadily decreasing since the original 2, although TOK was a slight improvement over CS.
