What's better for code speed: All path to object or variable with reference to that object?

Hello. I’m making my plugin.
And I have 1 small question:
What’s better:

local Object = Workspace.Folder1.Folder2...FolderN.Object
Object.Color3 = Color3.fromRGB(0, 0, 0)

--or

Workspace.Folder1.Folder2...FolderN.Object.Color3 = Color3.fromRGB(0, 0, 0)

I don’t really need good readability in code bc I’m solo dev, but I need know, what’s more performant?

if you use the object multiple times in a script, by practice its better to use variables just for the sake of productivity and readability, but if you’re only editing it once then there’s no need for a variable
