OEM. I've had to warranty and eat so much labor from faulty auto parts store starters and alternators it's unreal. They cost more, but I rarely have an issue with OEM.
Pros: rarely have issue
Cons: cost more

If you can get motorcraft, that is my recommendation.
Pros: Ford oem parts
I kept driving it and it eventually completely lost voltage. Threw another Denso in there and it’s golden.
Pros: it’s golden
Cons: completely lost voltage
Put a Denso rem one from Rock Auto on my 07 and it was great.
Pros: great Denso alternator
Vehicle:
Toyota FJ Cruiser
I would not cheap out on an alternator, especially if you’re having a shop install it as paying for labor to replace two low quality alternators is equivocal to one OEM.
Pros: OEM parts are better
Cons: low quality alternators
You want your input(alternator) to go to your storage(battery box) and then hook up anything that will take power to the battery box.
Vehicle:
Land Rover Discovery
I've got the flickering lights so I'm going between the Denso reman and Bosch reman. Looks like the Bosch reman is done in house and the germans have pretty good engineering imo.
Pros: good engineering
Cons: flickering lights
Newer ford alternators essentially “talk” to the pcm. Cheap aftermarket alternators do not do well on these cars. Replace the alternator with a better quality alternator
Pros: better quality alternator
Cons: cheap aftermarket alternators
Vehicle:
Ford
Denso is usually one of the top ones, if they've tanked in quality I shudder to think how bad oem GM, and mopar/stellantis has gotten. I still have nightmares from absolute shit quality of GM parts, alternators and starters barely lasted over a year.
Pros: null
Cons: quality has declined
My 2020 Mazda cx30 has a bad alternator at 47,000 miles. Bought this car about a month and a half ago. Wondering if this is a typical thing for Mazdas alternators to go out fast.
Cons: alternator went out fast
Vehicle:
Mazda
Mileage: 75639 km
