Wow. My experience is completely different. Not saying your experience is not what you had. But it is not how it plays out for me. I have used my 10" Dob side-by-side with my Apos for a decade and yes the 10" gets more details for planets, but at an operational cost. With the 10" one looks for those "moments of best clarity of the view" as the instrument tries to deal with the seeing and its own thermal quirks. With the refractors the characterization of the views are just the opposite as the views are for the most part always completely rock steady long term. Plus, in reality, having done so many side-by-sides, quickly realized that for the most part, the seeing controls the details -- and no way everyone out there has sub-arcsecond seeing most of the time. So when you do enough observation sampling, you quickly realize the more detailed views from the larger aperture are less often than you think. If one just goes out to observe a few times a month then statistically easy to hit a stretch of better seeing evenings skewing ones perspective. And I do have a 6" f/8 Apo and it is not a beast by any means, And when you mount them on simple alt-az mounts the entire thing is no more cumbersome than my 10" Dob to move around. And finally, while larger aperture has its place where it outperforms, like on faint fuzzies, a 10" that limits you to less than 2 degrees TFOV will mean you are missing a lot of nice open clusters and larger interesting vistas. And when the seeing is limiting magnifications, can also force you to have to move to filtration to reduce the brightness of the planet as too bright obscures features. So my experience is that the act of observing a planet has a lot more going on then simply level of details. I personally find the entire process more effective and more rewarding with a smaller refractor than with a larger mirrored instrument. That's my experience. So folks should understand both your experience and my experience as it is not a slam dunk in either direction. Where it falls for them will be something that they have to figure out in the field as it can swing either way.
It sounds like you have been observing with APOs for years and I have no doubt that you are a more experienced observer than I. The 152ed was not mine and I don't own an APO that large. The dob and SCT are mine, as well as two medium sized APOs, 110mm and 127mm and several much loved achromats. I did however have near exclusive access to the larger APO for a little over a year, thanks to a very kind work colleague, and I enjoyed the view through it so much that it made me a refractor observer convert. I may be incorrect due to my less observing experience compared to you, I am by no means the expert here, perhaps I have just yet to observe under the conditions that would allow the smaller frac to outperform the larger mirror. Though I still stand by suggesting the OP a larger apature reflector vs smaller refractor for lucky imaging Mars this year, which is the OPs intent.
