Django or redsolutions?

About the same stage I, but the fact still on Django wrote "project Manager" for their organization.
\r
tepet for Django, rewrite one website that I wrote 2.5 years ago in PHP + Joomla...
\r
IMHO, after jabuka early to Suva such as Django CMS \\ resolutin
more experience is necessary, for example, try in the admin to change the functionality a little bit to the side, and not just to change the display and sort fields

After mastering the Django at a certain level — I recommend to use DjangoCMS.
\r
Already half a year do not use this stuff, but it is very convenient DjangoCMS to use in conjunction with django-admin-tools (decorations admin).
\r
DjangoCMS pros: a lot of plugins, a new written easy, I18n, blah-blah-blah. And, most importantly, it is not too changes the very framework.
\r
Pros django-admin-tools: you can quickly and easily assemble a custom admin area that is not ashamed to show to the customer. In the same vein, project grapelli, they say, very well WildAid.

And how much time?
If you have time of course Jung. If not — see the specifications Ski, is it possible to do "in haste".

In any case django itself to study deeper you will have to better understand the issue. But in addition Redsolution CMS and DjangoCMS, there is the GAE framework (though this, of course, that framework, but like django and makes up for the disadvantage that in GAE django is not fully supported), which are also worthy of study.
\r
Which is better? I agree with what was written above: if you have time — learn more django. If there is no time or desire — use CMS, and some choose to taste, the more that the choice is not very large :).
