Funny enough, I just did this dance today! Found a nearly new looking Bosch unit that someone had already kindly removed from the wrecker's car for me. Got it installed and tested exactly like yours though, so I'm happy.
Pros: nearly new looking, happy

I picked up a 07 jetta 2.5 from the auction for a good deal and only 95k on it. The problem is the battery is not charging, figured ok needs new alternator put a bosch unit in and it is still not charging the battery. Put multi meter to the post on alternator and it is only putting off 11.5v.
Cons: not charging the battery

There is a Bosch unit that will fit with the same connectors, but the pulley is usually different. I went to a local auto electric shop and they asked about the current I wanted at what revs and they built a Bosch unit with the appropriate coils and fitted my old pulley. Plug and play, and it's been flawless for 10 years or more.
Pros: plug and play, flawless
Cons: pulley is different
