Bosch is the OE manufacturer for motorcraft alternators so if you find a Bosch chealt cheaper, go for it. They're the same minus the motorcraft sticker.
Pros: OE manufacturer, cheaper option

I recommend DB electrical for a stock, everyday use replacement. I have one going for about 4 years now, and I abuse it heaving as it's on a truck with a plow motor. Want the best in the business? Get a Denso alternator, they will last forever.
Pros: lasts for years
That Bosch VR6 alternator was not a direct fit, but significantly easier than the Delcos other Rover owners commonly used. My method was faster, cheaper and way more reliable.
Pros: faster, cheaper, more reliable
Cons: not a direct fit
Vehicle:
Rover
Bought new alternator TYC from rockauto. with a volt meter, I checked for voltage at the alternator B+. it charges at 14.2 when reved to 3000 rpm then it gets to idle, it remains at 14.2.
Pros: charges at 14.2 when reved

Chevrolet HHR
Get a Bosch or Denso alternator. I'd buy used before one of those brands. Just my preference, I know they sell tons of starters and alternators, but I don't like to do things twice.
Pros: reliable, long lasting
Cons: may need replacement
270 amp Singer Alternator, 10K miles on it
Pros: high amperage, low mileage
Mileage: 10000 km
Update: There was a direct short in the alternator and when it shorted internally it also took out the 200 amp protection fuse ($115) too for the battery. I got a new Bosch unit and I was happy to find out I did not have to bring it to the nearest dealership and that a local German repair shop were able to do it.
Pros: new unit, local repair shop
Cons: direct short, protection fuse
Vehicle:
Volkswagen Jetta
Mileage: 47800 km
Funny thing is, the Bosch alt. I had in the car at the time is sitting in the car in my driveway. Okay, I replaced the brush pack a few times. The 90 Amp alt. itself is at least 10 years old, if not more.
Pros: at least 10 years old
Cons: replaced the brush pack
If you put a Botch on a Honda, it will last about 3months.
Cons: lasts about 3 months
Vehicle:
Honda
I had an issue on my 88 300ZX where a failed alternator burned out the ALT link. This is a connection between the alternator and the battery.
Cons: alternator burned out ALT link
Vehicle:
Nissan
