Obviously, Tsuji is the first and only one of the current gen guys to reach the “mountaintop” but it feels like those other three have made good enough impressions to be at the top in the years to come. You obviously have to consider Umino & Narita as well but they do feel behind those other 4 in terms of development, imo (at least when it comes to their ceiling belong lower).
Of the “4 gatekeepers”, only Taichi hasn’t won the IWGP (and does seem unlikely to ever hold that Title) but it does feel like he belongs with those other three in representing an “older guard” for the current guys to feud with.
