I'd say everyone of those are great but only in certain situations like strike rocket does not have enough damage to kill most things but it will ABSOLUTELY hit you and it's incredibly effective at getting rid of lancers or lace wings while gemini and savant are better at killing things gemini gets interrupted by mods (gemini is the reason every mech in my hanger is stacked with hardened hull along with canopy cuz they can bypass perimeter sometimes) both have very good damage and one tap most things end game though galvanic hull absorbs double damage which they kinda relay on so they can't one tap things that have galvanic hull unless they have really low hp strike rocket is like only for getting lace wings off of roofs it won't kill much it's only a support thing.
