We study the spectra of two-gluon glueballs and three-gluon oddballs andcorresponding equation of state in $5$-dimensional deformed holographic QCDmodels in the graviton-dilaton system, where the metric, the dilaton field anddilaton potential are self-consistently solved from each other through theEinstein field equations and the equation of motion of the dilaton field. Wecompare the models by inputting the dilaton field, inputting the deformedmetric and inputting the dilaton potential, and find that with only 2parameters, the $5$-dimensional holographic QCD model predictions onglueballs/oddballs spectra in general are in good agreement with latticeresults except two oddballs $0^{+-}$ and $2^{+-}$. From the results ofglueballs/oddballs spectra at zero temperature and the equation of state atfinite temperature, we observe that the model with quadratic dilaton field cansimultaneously describe glueballs/oddballs spectra as well as equation of stateof pure gluon system. The model with quadratic $A_{E}(z)$ can describeglueballs/oddballs spectra, but its corresponding equation of state behavesmore like $N_{f}=2+1$ quark matter. These are consistent with dimensionanalysis at UV boundary.
