usually there are different ways to perform a task and sometimes I'm unsure which one to prefer.
E.g. like these two ways to transfer the rotation from one object to another in Python.
obj_2[c4d.ID_BASEOBJECT_REL_ROTATION] = obj_1[c4d.ID_BASEOBJECT_REL_ROTATION]
The outcome is the same here but is one way better than the other and why (e.g. performance-wise)?
I'd intuitionally tend to the first method but I'm not absolutely sure if it is really superior to way 2.

This is covered some on a cineversity wiki page, although it doesn't use the exact examples you have:
They don't get into object methods like SetRelRot(), so it'd still be interesting to find out if there's a big difference there.

The fastest way is the first with SetRelRot().
darby linked an interesting page on Cineversity wiki, where there's a nice explanation why using the subscript operator  is slower.
In the end, performance isn't so important for most scripters and using  isn't wrong for object's parameters.

Hi Darby and Yannick,
thank you both of you, also for the wiki link.
So I had the right feeling indeed.
