  This paper studies both $\Lambda$CDM and CDM models under the \"uber gravity
theory, named \"u$\Lambda$CDM and \"uCDM respectively. We report bounds over
their parameter phase-space using several cosmological data, in particular, the
recent Pantheon+ sample. Based on the joint analysis, the best fit value of the
\"uber characteristic parameter is $z_\oplus = 0.046^{+0.047}_{-0.032}$ and
$z_\oplus = 1.382^{+0.020}_{-0.021}$ at 68\% confidence level for
\"u$\Lambda$CDM and \"uCDM respectively. Although \"uber gravity can
successfully mimics the cosmological constant, we find that the
$\mathbb{H}0(z)$ diagnostic suggests the $H_0$ tension is not alleviated.
Finally, both models are statistically compared with $\Lambda$CDM through the
Akaike and Bayesian information criteria. Both \"uber gravity models and
$\Lambda$CDM are equally preferred for most of the single samples, in
particular, \"u$\Lambda$CDM is not rejected by the CMB data. However, there is
strong evidence against them for the joint analysis.
