For starters, I'm unsure of the potency the Auto-9 has, but based on their standard equipment, neither can realistically harm each other with weapons fire until the Plasma Rifle comes out.
Even if they are relatively the same strength-wise, this means they physically have a
hard time hurting each other as well, as they are much more durable by comparison.
In close quarters combat they are even, not considering the movement speed gap as per RoboCop's generally slow travel, as they both are capable of catching bullets.
RoboCop has the jetpack however which will give him the movement advantage as well as flight, meaning he can stay out of the T-850's grasp which, depending on which LS we use, could be a problem or not.
In terms of staying power, Terminator will undoubtedly last longer without needing a break, as RoboCop only lasts 24 hours without charge and being damaged can drain battery, whereas the Terminator can last a century on a single power cell.
I'd lean RoboCop only because Tactical Ordinance when cranked up in level can be more devastating and the terminal strip being a natural defense tool so he can have the advantage while unarmed if it comes to that.
5.5/10 for
RoboCop.
