[5] On this tour, the duo performed the then-unreleased songs "MeMeMe", "Hollywood Baby", "757", "Billy Knows Jamie", "One Million Dollars", "Hey Big Man", "Fallen 4 Ü", and "What's That Smell?".

[14] Writing for PopMatters, John Amen noted, "The duo reaffirm their status as hyperpop ambassadors while implementing a notable mainstream savvy, including memorable beats, hook-ish melodies, and vocals that epitomize an au courant slacker vibe.

"[19] Reviewing the album for AllMusic, Fred Thomas suggested that it, "expands the duo's cultural collaging to include cannibalizations of Limp Bizkit-style nu-metal, pop-punk, '90s alt-funk, ska, and anything else that captures the gecs' fleeting attention."

"[15] Reviewing 10,000 Gecs for The Sydney Morning Herald, Robert Moran wrote that the duo had not been tamed by signing to a major label or feeling the pressure to follow up the "free-form fluke" of their debut.

[21] Deeming it to be perhaps "the weirdest major label release" since Ween's Pure Guava (1992), Moran wrote that "10,000 Gecs is hilariously extreme, a nutty and unbridled celebration of pop culture detritus befitting the synaptic overload of our perennially online era.

"[21] In June 2023, Alternative Press published an unranked list of the top 25 albums of the year to date and included this release, calling it "10 times more ludicrous than its precursor" with "the raging moshpit of nü metal, cyberpop, emo-rap, ska, and punk that somehow wrestled mainstream critics onto their side of the joke".
