My main task has been to guide a spectroscope with a 20micron slit on a star image for as long as possible.
I'd prefer using the Celestron or the Lumicon to the Meade. They allow better control of finding and locating a guide star. I find the Celestron easier on the SCT, BUT with the #1209 micro zero shift focuser on the LX200, the Lumicon does a very good job.
I didn't mention, but I'm also testing a Vixen "clone" 50/50 beamsplitter as a guide. This allows full field coverage and "only" costs about 1 magnitude in image brightness. Even with the light loss, it's proving to be very easy and very user friendly.....
