A lot. Haile is one of the single best jack of all trades units in the game (All-stat buffs? check, BB mod? check, BB management? you must not know who she is) and Tridon can singlehandedly cheese you through trials due to his awesome LS (40% hp, 50% rec, and 10% mitigation make for a very defensive package), along with his shield (his trademark buff that gives a "second" hp par which must first be depleted/removed before dealing damage to your units). Both of them are incredible assets in most content save FH really (Tridon sucks at dealing damage and Haile's buffs clash with a lot of preffered damage dealers such as Avant).

For that squad I suggested, Haile is an excellent alternative lead (30% all stats, 25% boost to the chance at generating BC and HC, a 50% boost to your BB gauge fill when picking up BC, and an extra 150% damage to BB/SBB/UBB because why not?), and effectively kills Nadore as the all stat buffer, while Tridon can be a very good alternative for Limera since the barrier blocks all damage types and his BB has a powerful heal/turn effect that directly counters the damage on turn debuff some bosses may use.
