Personally I'd choose Byakugan (Not in the Narutoverse but IRL)
See inside peoples bodies = Lie Detection and Cancer/Disease Detection
360 Degree Telescopic Ephemeral Vision = Find Everything I've every Lost, Increased ability in nearly all sports and other talents
In real life the others except for basic Sharringan seem far inferior in terms of real life usage than in the Narutoverse (Not Bashing Sharringan and Rinnengan just saying they'd be less useful in my life than in say Naruto's life.)
Basic Sharringan: Still really cool; Reflexes, Mimic other peoples actions (super muscle memory), Genjutsu's Nice, Sensing people's cool.
Susanoo (Scaring people and emergency protection.)
Tsukuyomi (Why not just use regular Sharingan genjutsu, It's not like they can break free of it and the only other bonus is torture.)
Amaterasu (I don't plan on commiting Arson anytime soon, just saying.)
Kamui (Here's a useful one Nearly infinite storage and fast transport.)
KA (Same as Tsukuyomi why bother not use regular genjutsu and why bother with this one if you can only use it once a decade without Senju DNA.)
Izangi (Change your life lose an Eye.)
Izanami (Change someones perspective lose and Eye.)
Deva (Protection, Throwing things, Grab stuff from across the room.)
Human (Mind Reading.)
Animal (I don't plan on fighting godzilla. but that's just me.)
Naraka (I don't plan on torturing anyone anytime soon. Might change my mind but probably not.)
Asura (Again no plans for Arsen.)
Preta (Could take someones stamina or absorb fire.)
Outer (Maybe if I just watched a hole lot of people die... Maybe.)
Again Not Bashing... They're not useless, they're all still cool, but they lose usefulness in the life of an average person vs a life of violence and action.
