I need a new N75 valve since the old one makes noises when turning the engine off.

The standard one on my engine code ATD is 1J0 906 627 A . I wonder if fitting a newer version 1J0 906 627 B would be even better (last longer, provide better acceleration, etc.)

My engine code is ATD with 101 hp and the AXR, also a PD TDI, uses the 1J0 906 627 B . The AXR is only slightly different from the ATD, mainly to meet emission regulations in Germany (fun topic, I know... ). Then, even the VW Beetle with the ATD engine uses the 1J0 906 627 B .
The ports on the 1J0 906 627 B point in the opposite direction (compared to the 1J0 906 627 A) but that is no big deal. I can lenghten the vac lines just a bit.

So, does anyone know if fitting a 1J0 906 627 B on a MKIV ATD has any advantages over the 1J0 906 627 A?

It's probably that part number because it has different orientation, you will likely find the same components inside.
You can also rotate them back to whatever angle you need. No they will not provide any different acceleration, that's not what they do.

Original N75 easily lasts over 200,000 km, so I am not sure anyone has looked for upgrades.
