What would be more efficient in terms or performance for my doors?

I want to start off by saying that I couldn’t find posts on this topic before, but because I only did a quick search, I apologize if this has been asked before.

I’m making doors for a bunker, and I’m wondering if it would be more efficient to use negates to create a hole for the door, or to use several parts that create a gap. Which would be more efficient for performance? Or is the difference negligible? There’s going to be about two-three dozen doors. Thanks for your help!

Images if my explanation wasn’t clear:

Using a negate

Using several parts

Thanks for everyone’s replies! If I could mark all of you as the solution, I would.

Technically speaking, having less parts is better, if negating causes you to use less parts, go for it. But sometimes negating makes the hit box a bit odd

If you make a union out of the wall and the negative part, your resulting collision box might not fully align with the visuals of the door, creating a hole which is possibly wider or smaller than it looks. I would highly recommend using just a few parts. The performance cost of a couple parts is almost 0 anyway.

Either way, you’d probably still use several parts.

If you negate, it’ll turn whatever you union that negation with, into a union, so that means it’s harder to scale certain parts of the union, without separating the union, then having re-union it again. Also you cant have multiple textures, or change one part’s color, if it’s in a union, without adding a new part.

If you use several parts, it makes it easier to scale parts, but you may have issues with positioning it. (Any thing that goes in between the door frame and the multiple parts) It does make it more efficient to change colors or textures of certain parts, without having to change them all.

If I were you, I’d use more parts, rather than union-ing it.
