Absolutely this. Not sure if the IGN is related to Japan too but you can clearly see there who's the most popular pokemon of all time. (and it's not Pikachu)

Infernape had its main focus in DP but Imay agree with you that he's the only regional powerhouse who hasn't battled a legendary yet. It was in the Sinnoh league.
Torterra (even though it's my favorite genIV starter) lost everything after fully evolving. Many people may say he lost to very powerful pokemon, but the point of being strong is to be able to defeat those strong pokemon. It was in the Sinnoh League.
See the diference? those 3 were absent for 2 years, Charizard was absent for 6. There's no point of comparison.
