Burgundy:
Trade: 2

Burgundy has access to one or 2 sea ports, and some lands to build towns. They have enough resources to trade. Maintenence costs are very high though, which is an important issue in the first centuries.
Production: 4

Lots of productive resources around the capital. The Rhone valley and Toulouse are rather productive too. Important note: all cities can become productive with towns and levees. I've left that part out now.
Culture: 4

Because of it's resourceful capital, even better if you settle Besancon, which is SSW, you can get some early wonders. The UP is also powerful for new cities, so I'd give culture 4 or even 5 stars.
Growth: 2

Large cities are possible, when the entire valley has farms. Otherwise, the cities stay small. There is not much room for expansion either, you won't get much farther than Barcino, Milan and maybe somewhere between Germany and France.
Starting situation: 2

There are some dangerous neighbours very close: Germany and France. The other things seem to be fine, so 2 stars is reasonable.
Overall: 14
Byzantium
Trade: 2

Byzantium has large penalties, although there are some possibilities for them to do a decent job. Especially Constantinopolis means a lot to them.
Production: 2

Raw production is not bad, but the modifiers are annoying. It's the same story as above: Constantinopolis is the important city.
Culture: 4

An early religion, early wonders, Byzantium has it all. However, 4 stars because it's hard to construct all cultural buildings in time because of the poor production.
Growth: 1

It takes ages to grow the cities. Anatolia lacks food, and the magical penalties strike again. Don't even try to expand, the cities flip away as soon as you build them, which is a complete waste of the many hammers that you've wasted to build a settler. The only positive note is Constantinopolis (again), that is soon limited by hapiness and health caps.
Starting situation: 5

Yes, 5 stars here. I think this is one of the most arguable decisions, that will have to be corrected but this is my opinion. Nothings seems to be wrong when you start; even better, you seem to be a world power. Normalized score says everything, 100,000 points for winning this turn.
Overall: 14
France:
Trade: 4

France has access to multiple Atlantic ports. They have lot's of good land, and some resources to trade as well.
Production: 3

Paris has high capabilities, but the other cities that you don't have to conquer are not that good for production. Maybe 2 stars is better but it's still very possible to conquer the territory needed to get a high production.
Culture: 3

The same deal about the wonders, but France doesn't have the same UP. So, three stars is what they get.
Growth: 4

France can hold large, wealthy cities. New territories can be conquered easily thanks to the UP.
Starting situation: 3

France has a decent situation. There is some barbarian pressure, Burgundy can declare war early, England can get a food on your land but these things are not so terrifying.
