I'm testing both K2 and flexi. I really hate that K2 doesn't use core com_content. For example, I use Myblog right now for blogging. So moving to a CCK is a piece a cake cuz it uses com_content. Lets say I get a site built with K2, then something comes along and I decide to change for what ever reason, I have to get my data out of K2. That means, dumping data and trying to import into other tables etc etc. (a big head ache). Along with that K2 doesn't seem to be compatible with lots of content plug-ins like scrollers, tabs, content rotators. The one plus i give K2 is its more polished on the front end and looks much better. Flexi needs lots of template work to make it look good.

I'm just really surprised K2 decided to use its own set of tables. Maybe I'm just old school with database design, but more tables just seems wrong to me. Plus data portability is a major issue as well.

sorry for not posting back been busy.
I have used most of the ccks out there even JSebloc
basicly all cck's are lacking.
not a complaint just an observation
the reason is that they are all still new.
Maybe just a year or ywo old

JSeblod Rocks except it is difficult to learn.
I think Flexicontent needs time to mature.
FLEXicontent is conceptualized with J1.6 in mind
also there is FLEXIacces which absolutely rocks.
the combination is seamless. I can't wait for all this to come out of beta?
But its better that they eait and have an awsome product

I'm not knocking anybodies software. I still use K2
cheers
this is a great discussion
PS thanks for the spreadsheet looks great Nice comparison
