I love the old world feel of Britechester, it's sooo pretty. And it's smooth to follow sims, and they don;t take too long to get anywhere.
Foxbury drives me nuts, to the point I feel it's completely unplayable, which makes me so sad because it's also a beautiful design aesthetically. But if you are following a sim anywhere, the camera shoots around all over the place, shoots up into the sky, I feel like I'm constantly readjusting the camera and I can't just look at my sim from the angle I want to without 3 hours of moving the camera around first! Plus like the above post said, there are so many stairs that if you try and ride a bike anywhere your sims will miss their classes because they'll still be taking their bike out/putting it away at one of the stairs. It does have a cycle path type design that you can use, but they never use it automatically, and you have to click on different sections of it to get them to use it at all.
What I've done is designed a completely new campus in Oasis Springs for all my Foxbury students, because it's the only way I can play it, and I like my sims to do distinguished degrees (I thought science sims and being in the middle of the desert is a bit Area 51 ;) ) But yeah, Foxbury is pretty but completely unplayable in my personal opinion, unless they live off campus.
On a different note, a good tip is that once a sim is in class, you can click on their icon at the bottom of the screen and choose options, like "Take Notes" or "chat with friends". (like when sims go to work), so clicking "take notes" definitely seems to help the grade!
