The datasets incorporate the Cosmic Microwave Background (CMB), Baryon Acoustic Oscillations (BAO), Cosmic Chronometers (CC), lensing, and Pantheon supernovae. We compare the ability of these models to bridge the discrepancy between Planck 2018 (\\(H_0 = 67.4 \\pm 0.5 \\ \\text{km/s/Mpc}\\)) and the local R22 measurement (\\(H_0 = 73.5 \\pm 1.04 \\ \\text{km/s/Mpc}\\)).
