Well, the main problem is that of the ones that were discussed, two of them (specifically Awstats and Webalizer) are both server-side systems. Great if you are on your own host and can instal back-end software, but useless if your comic is still hosted here on CG. If you do have your comic on your own host, then I would recommend Webalizer over Awstats as it is maintained better and there are newer versions availble.
Getting a good statistics program that will tell you what you need to know is pretty hard, especially for webcomics. I've been running searches since I replied to your first post trying to find good, informed discussions on what type of programs work best for webcomics but the one I linked to is still the only decent one I have found. Most of the others that are around are either too old and recommend programs that are no longer available, just say "use Google Analytics" or "use your host's stats programs".
If your comic is still on CG, then I think GA is still pretty much the only one that is recommended, even though it gives less than desirable results for webcomics.
