Perception or Cognition?

There's a new version of Perception released on XDA and I've read about it moments ago. I'm just confused which one to use, the Cognition or the Perception? Can't decide which one suits me cause both of them looks amazing based on the logs.

So how's Phoenix? Is it better than Perception and Cognition? I also want to try different ROM, but how? Do I need to do all over the steps like flashing the stock, then master clear from odin then clockwork then the ROM? Or is there any alternative step?

I just flashed Cog 3.03. Pretty darn good and stable. Only glitch I found is that the contacts page wont back out with the back arrow feature. Other than that a very good mix of stock 2.2 and custom. Great work

I've tried Cognition 3.0.4r2 and Perception 10.2. They are both similar to each other and no not include much of the "custom themes" thing that many of the other distributions seem to have. I've noticed a few differences and have found the Perception build to be nicer for me.

Some differences:
* Perception fixes the bug where when presses the on/off key to turn the screen back on, the phone would display what apps are open before the lock screen is shown.
* Perception allows the HSUPA data protocol which should increase the data rates over the cell modem.
* Perception does not come with LauncherPro. Cognition comes with LauncherPro.
* Perception enables auto-updates of the Google applications. I'm not sure if Cognition does or not.
* Cognition is 2.2 while Perception is 2.2.1
* They put lots of sites in the hosts file to block them (ad-sites). Perception kept trying to connect to the google analytics site in an infinate loop (with a short delay). This could use battery power (but not data). I'm not sure if Cognition does this
* Perception uses "voodoo sound". I've noticed that there is more background noise (faint hiss) when using headphones.
* Perception gives an option of "video chat", though I've never tried it.
* Perception does not seem to be able to enable both the "silent" and "vibrate" modes.When one uses the volume down button, it ends on either silent or vibrate....  Cognition was more like stock 2.1 in this regard.
* Cognition perhaps does not allow as dim of a brightness setting.
* I'm having issues with the prox sensor not detecting my head very well on Perception.
* Both firmwares have a 802.1x related wifi bug where the phone crashes (and restarts itself) in my building (Stock 2.1 also had this issue).

That's all that I can think of for now. What are other people's experiences?

I agree that choosing a ROM based on the apps it come with is mostly silly, but I just wanted to point out the differences that I had noticed. Regarding the video chat, I was thinking that it would instead use the rear-facing camera. Or is this something that AT&T's network would have to support?

For brightness, I might have been mistaken. I was thinking that the minimum level (when using the brightness slider in settings) was a less bright. I don't have two Captivates so I cannot really tell. I think that the auto-brightness may also have been effected.... Again, I'm not completely sure, so perhaps someone else could comment if they agree or disagree.
