SCT vs DOB on planetary viewing??

Hi everyone. Would like to throw a question out there for you guys on planetary viewing and telescope suitability.

I own an 12 inch LX200 ACF SCT which is well collimated and has good optics from what I have seen. I have observed Jupiter and Saturn on many occasions. 380X seems to be the sweet spot here in Perth where seeing is good enough to crank up the power to get in close on your object.

Saturn has always produced a real wow factor without any trouble.
Jupiter, however, has been either just o.k. or disappointing....... even after sufficient scope cool down time and average to good seeing and transparency.
For some reason, I have yet to see the small white ovals and other fine details that people report on the forums.

My question is................should I be considering a 20 inch GSO dob(coming soon) or even a 16 inch as a better option to obtain higher resolution through larger aperature/smaller central obstruction?

How do the 16 inch Skywatcher and lightbridge perform at higher power on planets?.............or are the optics only good for DSO's.

Would love to hear your thoughts
