Drivers are pretty heavy, if you plan to keep them in your fixture there is a benefit in only using one. What concerns do you have? Drivers last long, and there is a certain flexibility that comes with smaller sizes... there is also some convenience in just hooking up a single driver.
I have 10x75w drivers. Lacking a dialed in setup I keep on having minor benefits from flexibility, one seed was an auto so I separated the plant with a 75w light. Another plant seemed to have the tobacco mosaic virus so again I moved a light and the plant to a separate area for observation, and filled the rest of the space with salads and herbs.
Every time I set an area up for flowering it gets frustrating, there are more wires to deal with, and drivers lying around everywhere.

well I've just seen a few bigger builds where they used two drivers when hey could have just used one big one. so was just curious if there was a reason for that.

If I was marketing a light with multiple drivers, I would probably talk about the security it provides. Even if a driver popped, you would not mess up your light cycle. I would not expect anything to pop though.
If I was marketing a single driver light, I would probably talk about weight and resulting practicality - which I would enjoy every time I move the light.

I will add that the 320 has 94% efficiency while the 600 rocks 96%. That's the price of convenience.

ya I noticed that. I went with the 600 for that reason.
