Standard gear for Sam is quite broad. In Blacklist he has an array of sonar goggles.
Colorized Imaging (provides Thermal imaging)
Even with standard night vision, Sam has more advanced tech ranging from lethal and non-lethal divertive, he has a tri-rotor. Smoke, tear and sleeping grenades. Flash bang, frags, incendiary grenades. Proximity mines etc.
I do think Ezio is more adept at tracking down targets for the fact that he is a trained assassin whereas Sam is a spy that goes on covert assignments. This probably puts Ezio as the hunter and Sam as the hunted. This is a toss up in anyone's favour. Should probably specify Sam's gear.
