Bayesian constraints on seven w(a) parameterizations with CMB+BAO+SNIa datasets favor the logarithmic model over LambdaCDM in several combinations and show modest sigma8 relief.
Under the constraints of CMB+BAO+DES-Y5, the H0 tension of all DDE models reached the maximum value among the three datasets
