600D/550D has a teeny tiny OVF, no AF-C in video mode, very low dynamic range, about the level of M4/3 (see dxomark site), No wireless flash control on 550D, slow AF in liveview mode (even Pentax is faster), low frame rate, small buffer.
I will rate them as such
(1) A55
(2) D5100

(69) 600D
(70) 550D

...and, you see, here's where I think independent review sites, like DP Review, can really help - though I appreciate you don't like their reviews, and that's a personal choice - because they at least give you the parameters they're reviewing against and you have a higher level of assurance that they're taking a reasonably unbiased view... it's not an absolute assurance of lack of bias, for sure...
But what you will get from the answers here are opinions, based on different experiences and with at least the potential (I'm not accusing anyone!!) for differing degrees of bias...
It might have been helpful if I'd added after my query - "better in what respect?":-
The list of what's important would be up to you - it's your list
Below is a suggestion. It's used in all sorts of decision-making... it's based on the idea that humans become selective in the factors they attend to when making decisions, because we find it difficult to keep more than a limited number of things in our attention at the same time... so we have the potential to forget something at one moment that we knew / thought was important at another (e.g. my decision, with my wife, to buy a bed that would never fit up our cottage stairs... oooops, forgot that factor...!! Yes, I got a refund..! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='
' /> )
Ok, so the suggestion is you make a list of what's important to YOU about the new camera (and maybe the lenses)
Weight the factors according to the importance you attribute to them - for example if build quality is really important, you might give it 8, 9 or 10 (if use a 10-point scale)
Video might be less important so you might rate it 2, 3 or 4... the numebrs are up to you...list the factors, put them in an order, then weight them
I'd use a spreadsheet, e.g. Excel, to do this... you list the factors, weight them, then rate each camera body (or other life choice..!) you're considering on a scale, e.g. 1 to 10
So for each factor you get weight x rating for that factor...
Add the scores for each factor, for each camera body (life choice)
Compare the scores
Now here's the interesting bit... you can get scores with this that make you think "That can't be right, that's not what I want to do at all..."
Which tells you the whole exercise was based on a spurious notion of accuracy in turning life decisions into mathematics... but at least it has helped you to clarify what you want to do...!!
Have fun..!!!

It might have been helpful if I'd added after my query - "better in what respect?":-
- Image quality
- Ergonomics and handling
- Features
- High ISO image quality / ISO range
- Video
- Viewfinder
- Build quality
- In-camera editing
- Autofocus accuracy and speed
- Shooting speed
- Cost
