For a hydrodynamical description of the quark-gluon plasma created during a heavy ion collision, initial conditions of a thermalized system are needed. In this work, a comparison between three initial conditions models (SMASH, TRENTo, and IP-Glasma) is made. General quantities of the collision such as the number of participants and the number of binary nucleon collisions are determined, and the transverse plane energy densities from the different models are compared, along with their eccentricity distributions, for different collision systems at RHIC and LHC energies. The collisions in SMASH have slightly fewer participants and significantly fewer binary nucleon collisions. TRENTo not only produces lower eccentricities, but also has smaller event by event fluctuations. In addition, the elliptic flow from SMASH is shown, as well as the momentum anisotropy, found to be higher in SMASH than in IP-Glasma.
