Ironically, of all the skins I own, Prime Vandal is one of the ones I'd be fastest to replace. Don't get me wrong, it's very very satisfying and I love hitting shots with it because the kill banner is one of the best in the game. But I love having great variants and Prime debatably doesn't have that, and it also feels very vanilla compared to others Vandals of the same tier or higher (e.g. Champions 2023, Imperium, Sentinels of Light, Kuronami, Overdrive, and Elderflame, to name a few of the ones I like). I have felt at times a little bored of it, albeit never for very long.
At the end of the day, Prime is satisfying as hell :D
