CMS Choice

I am looking to add a CMS (Content Management System) to the website that I am currently in the process of rebuilding. Initially I have been going back and forth on the two widely used platforms of Joomla and Drupal but am running into problems trying to figure out which is better for my situation.

What I am trying to accomplish with a CMS is having the ability to let non-computer literate employees make updates to the website without  having to go in via dreamweaver and make the updates. The updates will be happening roughly every two weeks on 1 -2 pages. I have read multiple forums listing the pros and cons of either platform but have struggled to settle with one or the other. Joomla seems to be the slimmer, more plug and play of the two, whereas Drupal seems to have far more functionality but a more intense setup.

My main concern is whether i can develop my site in dreamweaver then assign certain areas to Joomla or Drupal for content management, or is it necessary to use their site development tools to build the site?

Furthermore, I did notice that Drupal includes some SEO functionality which the documentation doesn't go into much detail about, but was wondering if anyone has any experience with it?

I am hoping to find a bit more insight to help sway my decision one way or the other.
