Best automotive camshaft position sensors according to redditors

Had the half check engine light keep going off and on on my 2011 r56s w/46k miles, talking with a couple of different mini experts they suggested I replace the solenoid valve(s) to see if it helped, along camshaft position sensor.
was very easy to do and haven't had and issues since

believe http://www.pelicanparts.com had a guide with pics that I saw but didn't follow, it was just a couple of bolts and some reattaching electrical connectors, very easy to do when you see the engine/parts

Solendoid

sensor

as far as the wiring harness, am afraid I am no help (didn't replace)

Here is the part you need if you're harness looks okay. Clean you're ground circuits as well as the corrosion on your battery terminals(which is normal).

Also, the coolant needs to be flushed, that looks nasty and rusty. There is likely a crack for that much to come out. Stop using water and use coolant.

I like denso products.

This is the one I bought. I suppose there's a possibility it could just be a bad sensor right out of the box.

edit: Looks like I may have bought the wrong sensor? Now I'm not really sure which one of these I need as comments on both show people claiming they work with the 7.3. Here's the other.

The one I bought is the F4TZ, this one is the F7TZ

edit 2: After checking with Ford the F7TZ is the right part number. Both will fit however.

I will do this as well. I dont know what type I should buy though. Google isnt helping me out much because I really don't know what I'm looking at. I found this one on Amazon that says will fit my truck.

Cam sensor. They usually are leaking. Might as well replace it. Mounted on the transmission side of the cylinder head. Two bolts to remove it.

So I believe after this thread I figured out the problem but can anyone tell me this:

Which one seems to be camshaft position sensor A?

just curious what the difference is between that one and this one:
