Dissecting the actual words of reviewers, they don't seem to agree.
And despite it's 84 Meta score, most in the industry would tell you that Forza isn't on GT's level (the same way Resistance nor Killzone are on Halo's level).
Not exactly a fair comparison when only one game out of those two Sony series' mentioned have been on "Halo's level" (if talking main iterations of Halo) : Killzone 2 with a 91 meta.
