The T-rex 600 has "presence" in the air when you fly it. It's a bigger and heavier model so it feels more substantial in movement. That's not to say it can't snap around like crazy, as it certainly can and is arguably one of the better 3D machines out there since it's a perfect balance between stability and performance, but it requires a significantly more expensive set of components to get that sort of performance out of it, whereas the EP550 can achieve similar levels of performance with fairly mid-range equipment due to how light it is.
Which is "better" is a matter of personal opinion. In terms of power to weight, the EP550 probably has the 600 beat by virtue of its size/weight, and with the right motor/battery setup you could probably get absolutely insane performance out of the EP550 that would make the rex-600 look tame.
But, at the same time, a t-rex 450 or smaller will be even more insanely overpowered than a high powered EP550.
It tends to scale like that in my experience, the smaller the models get, as their weight drops off drastically but power output can still be ridiculously high in comparison.
Naturally, though you gain more and more impressive power to weight ratios with the smaller models, they also start to become twitchy and fiddly. Some guys like their model to climb 100 ft in half a second, some don't. There are some trade offs going to larger machines in terms of aggressiveness, but at the same time you get some very nice benefits, rotary stability being one of the big ones, and visibility being the other.
I find the EP550 to be a perfect mix between the 600 and 450 class. It's got the aggressive authority of the small models but still instills that slight feeling of mass that makes 600 models often feel locked in and "right".
If I had to choose between the two, I wouldn't.  . I'd keep both and fly whichever one happens to strike my mood at the time.
All things being equal though, the EP550 is definitely a cheaper machine to run and you'll get more flight time with it if you're learning since batteries aren't nearly as expensive.

RE: My Hurricane 550's first Hover - 
. My H550 is under $700 complete with $100 battery packs instead of $250 to power the Trex. I am still learning stunts so repair cost wont be too much either.
