  The particle ratios $k^+/\pi^+$, $\pi^-/K^-$, $\bar{p}/\pi^-$,
$\Lambda/\pi^-$, $\Omega/\pi^-$, $p/\pi^+$, $\pi^-/\pi^+$, $K^-/K^+$,
$\bar{p}/p$, $\bar{\Lambda}/\Lambda$, $\bar{\Sigma}/\Sigma$, $
\bar{\Omega}/\Omega$ measured at AGS, SPS and RHIC energies are compared with
large statistical ensembles of $100,000$ events deduced from the CRMC EPOS
$1.99$ and the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) hybrid
model. In the UrQMD hybrid model two types of phase transitions are taken into
account. All these are then confronted to the Hadron Resonance Gas Model. The
two types of phase transitions are apparently indistinguishable. Apart from
$k^+/\pi^+$, $k^-/\pi^-$, $\Omega/\pi^-$, $\bar{p}/\pi^+$, and
$\bar{\Omega}/\Omega$, the UrQMD hybrid model agrees well with the CRMC EPOS
$1.99$. Also, we conclude that the CRMC EPOS $1.99$ seems to largely
underestimate $k^+/\pi^+$, $k^-/\pi^-$, $\Omega/\pi^-$, and $\bar{p}/\pi^+$.
