I've played it twice on the PS4 and while you do aim with your bow a lot, it's not exactly precision aiming that would require quick movements. Needing precision is only to start off the battle because once they become alerted to your presence, all bets are off and you're better off switching to melee or explosives/traps (or just ropecaster them and use strong attacks until they die). If you are using a bow after being discovered, you're either using elemental arrows (which don't require precision aiming) or tearblast arrows which do AoE damage to tear off components and weapons from the enemies. Not to mention the game has auto-aim, so you're never really struggling to light the Glinthawks on fire if they've discovered you.
So, there's really no reason to not play it on PS4 if you've already bought it once. If you don't own it for the console and still wish to play it, I would highly suggest using a controller anyways. The third-person nature of this game just feels better suited for a controller, but I grew up with the NES and SNES so action games feel more fluid with a controller for me.
