Sweeping with Continuous or 180 Degree Servo

I'm hoping my question is simple to answer. When wanting a sweeping motion, e.g., going from -30 to 30 degrees (similar to a grandfather clock pendulum), is it much easier to achieve this with a 180-degree servo? Would the code for this type of motion be more complicated for a continuous servo because those types of servos cannot track their position without writing code to do so?

Yes

You cannot track the position of a continuous rotation servo without external hardware no matter how much code you write

I appreciate it!

A continuous "servo" is NOT a servo. It is a gear motor whose speed and rotation direction can be controlled with a servo signal. There is no way to reliably and repeatably position the "servo" without adding a feedback element.
