Alright this purely depends on what you intend to do during your time playing, Suros Regime is good for PvP, the Monte Carlo is a good pve auto rifle, truth and ghyllahorn(can't spell for shit) are great seeking rockets(PvP and pve) icebreaker is a great sniper due to the ammo regen and void damage(great pve raid sniper) the last word and thorn(don't think you can buy then yet) were great hC until their accidental nerfs, but are still good none the less, the last word is great PvP HC but has a really low range but is the fastest gun in the west(lol jokes aside) thorn when they repatch it with the buff, will be an amazing PVP HC. Honestly you need to look it up...I personally had fallen in love with my two only exotics because of the challenge they posses which is the Monte Carlo and being able to take down Suros users. It all comes down to you what do you wanna do what guns do you prefer?
