  The study of identified particle production as a function of event
multiplicity is a key tool for understanding the similarities and differences
among different colliding systems. Now for the first time, we can investigate
how particle production is affected by the collision geometry in heavy-ion
collisions at the LHC. In these proceedings, we report newly obtained ALICE
results on charged and identified particle production in Pb--Pb and Xe--Xe
collision at $\sqrt{s_{\rm NN}} = 5.02$ and $\sqrt{s_{\rm NN}} = 5.44$ TeV,
respectively, as a function of transverse momentum ($p_{\rm T}$) and collision
centrality. Particle spectra and ratios are compared between two different
colliding systems at similar charged-particle multiplicity densities
($\langle{\rm d}N_{\rm ch}/{\rm d}\eta\rangle$), and different initial
eccentricities. We find that in central collisions, spectral shapes of
different particles are driven by their masses. The $p_{\rm T}$-integrated
particle yield ratios follow the same trends with $\langle{\rm d}N_{\rm
ch}/{\rm d}\eta\rangle$ as previously observed in other systems, further
suggesting that at the LHC energies, event hadrochemistry is dominantly driven
by the charged-particle multiplicity density and not the collision system,
geometry or center-of-mass energy.}
