Indeed, CA is overrated.
Of course, an APO or even an ED shows less CA, but, as said earlier, deep sky does not show CA.
I have an 80mm f/6.5 achromat, but is shows crisp images, even from the planets at 130x.
Admitted, a faint purple halo is visible at Jupiter, but not annoying at all. And bright (+2 or brighter) stars show blue halos, but that is all.
I have a 110mm ED which indeed shoes less CA, but the 80mm on tabletop tripod is a super G&G scope for quick viewing planets or deepskies.
And, indeed I prefer a short scope (even when it is just an achro) than a long rainpipe of 80mm f/12 which required a heavy tripod.
In the latter case, I pull my 400mm Dob outside within the same time.
