If you are hitting the same OG, then by definition you have the same concentration of sugars in the solution, so assuming the rest of your process is the same, then you would make the exact same beer, body, taste, and all.
That's really the major purpose of gravity readings and efficiency numbers: hit the same OG and FG and you can reproduce the exact same product batch after batch. Efficiency is just a product of gravity, so it works the same way.
