Pre-PS1: almost any Summon

FF7: Summons begin to become less and less useful as you face stronger opponents, forcing you use summons acquired later in the game (if you summon at all). Choco is one of the first all attacks you get but I've never actually cared for it.

FF8: Brothers, Carbuncle, Doomtrain, Tonberry, Cactuar. Also couldn't really take advantage of the Cerberus' tripling

FF9: Atomos

FFX: Nearly the same situation as 7
