  The sample of time-delay gravitational lenses appropriate for studying the
geometry of the Universe continues to grow as dedicated campaigns, such as the
Dark Energy Survey, the VST ATLAS survey, and the Large Synoptic Survey
Telescope, complete their census of high-redshift sources. This catalog now
includes hundreds of strong lensing systems, at least 31 of which have
reasonably accurate time delay measurements. In this paper, we use them to
compare the predictions of two competing Friedmann-Lemaitre-Robertson-Walker
models: flat LCDM, characterized by two adjustable parameters (H_0 and
Omega_m), and the R_h=ct universe (with H_0 as the single free variable). Over
the past decade, the latter has accounted for the data better than the standard
model, most recently the emergence of well-formed galaxies discovered by JWST
at cosmic dawn. Here we show that the current sample of time-delay lenses
favours R_h=ct with a likelihood of ~84% versus ~16% for the standard model.
This level of accuracy will greatly improve as the ongoing surveys uncover many
thousands additional lens systems over the next several years.
