I can see plusses and minuses to both. As you say, the hull design has more reserve buoyancy aft (presumably it's similar to the Marinaut 21 that way). That's good for modern heavy/large engines and gear. And the sight lines in the cabin are different, as you mention. Which is preferable depends on your height, to some extent.
I'd love to have the "magic carpet" ride of the 23, but on the other hand I would greatly dislike the hidden areas (such as how water gets under the cockpit/cabin sole). These things can be dealt with (which I can do), but having dealt with similar things in other boats, I love not having to even think about it. Virtually no hidden areas in my 22 (no hull liners, no permament "soles", etc.). But then I'm sure other people love those features and wouldn't trade. To each their own.
Will-C obviously loved his CC (and why not), but he often advocates towing with a 3/4 ton diesel truck. Not that you "need" one for a CC23, but perhaps it was a bit more comfortable given the extra 1,000# or so towing weight over the 22. But again, this may not matter at all to some folks - it all depends. Maybe you plan on a large truck anyway, already have one, don't tow, or are happy towing it with something smaller.
A lot also depends on what you can find and when and where you want to find it (if shopping used).
As in most things, I'd like to "cut and paste" for the perfect boat:
The "little boat that could" looks of the 22 (yep, I care - boats are functional beauty to me

).
The simplicity of the 22, both inside and out ("walls," cockpit sole, cabin sole, etc. on my vintage).
The sub-5,000# towing weight of the 22.
The fact that a 90hp works just fine (I only have ~75 now; still fine).
The slightly longer galley on the 22.
The "stick built" interior on the 22 (my vintage)
The hull shape of the 23, with the more reserve buoyancy aft.
The slightly larger cockpit on the 23.
Maybe the splashwell on the 23 (would have to experience it).
The larger foredeck on the 23 (haven't been on it, but I imagine it's nice).
There you have it, my personal cut-and-paste

I imagine everyone's would be slightly different.
Maybe they are getting closer now, but for me (used) the lower price of the 22 was a bonus. Lots left over to do whatever I wanted with vs. a similar 23 (at that time). I also have other things in my life than boating (now), and I feel less negative about laying up a less costly boat while I do other things. I don't know where the "line" is (for me, much less for anyone else) between that feeling and the feeling that it's worth too much to just leave in the boat shed while I do other things. It's somewhere, but I guess I wouldn't know exactly where until I felt it.
To summarize my opinion, there is no clear best - it all depends on your priorities and preferences. The two boats are more similar than different, in the grand scheme of boat designs (but details and preferences are still important).
