I've had dinner at both Akershus and CRT, but not breakfast, so I can't comment on the food quality at Akershus for breakfast. I've had dinner at BOG.
PRINCESSES: In general, the princesses are pretty similar between the two venues. Ariel, Snow White, Aurora, and Cinderella are among the "standard" princesses at both venues. Jasmine is usually the fifth princesses at CRT and Belle is the fifth princess at Akershus. At Akershus, you take the photo package photo with Belle (yellow dress) while at CRT the photo is with Cinderella. At BOG (dinner only) the Beast is available for photos after you eat. He does walk through the dining room, but he does not stop and take photos at that point. While it is very rare, he is not guaranteed to be there.
INTERACTION: I found the princesses at both locations to be equally friendly/interactive. I did like the set-up a little better at CRT. The princesses enter to a little fanfare (quick summary of the story; like three sentences) and then follow a set route. So once the first one goes by, you know that when next princesses reaches a certain table, it means you're next. No more having a princess show up and your is full! At Akershus, the princesses don't really have a route so you never know when one will show up. We even had the character handler come up to our table and ask if we'd seen a princess (in our case, Cinderella) yet because she was about to head to the next room.
GAMES: There are no games/activities at CRT. There was a princess parade at Akershus (at least there was at dinner). All of the kids were invited to parade through the dining room with one of the princesses.
FOOD: None of the venues have outstanding food, but honestly, folks go for the experience and the characters. From the Allears.net menu it looks like breakfast is pretty standard fare at Akershus. At CRT, all three courses were only okay, but nothing outstanding. Dinner at BOG was good, but again, nothing outstanding. It felt a little rushed.
ATMOSPHERE: This is where CRT really shines compared to both Akershus and BOG. Akershus is fine, but there really isn't anything "magical" about the setting. BOG can be amazing if you eating in the West Wing, but the majority of the tables are in the Ballroom and it reminded me of a large banquet hall/cafeteria feel. At CRT, you're eating inside Cinderella's castle! Everything about it seems to say "Disney" to me. Plus, kids get a toy wand or sword (adults too if you ask) and a wishing star.
COST: Being that you're on the DxDP, it doesn't necessarily matter as much about the cost. I guess economically, the Akershus/BOG combo is "better" because you take care of two meals, whereas for the same two credits at CRT, you only get on meal.
OVERALL: If you had to only pick one and budget wasn't a consideration, I would go with CRT because it had the overall better "atmosphere" and "experience". If you basing it entirely on food quality, I would probably opt for Akershus (assuming that it's hard to mess up breakfast) and BOG.
