I have and have owned a lot of P basses - current count is 6, including two PJs, all MIA Fenders except one Charvel.
Practically, technically, you won't find much difference. A split coil pickup in the same location relative to the bridge is just that - subtle differences between pickups and necks. However I get that a lot of what we do is outside the scope of practical and technical. You mentioned you have a strong feeling towards getting a P bass. In my experience, that's not going to go away until you get one and commit to it.
Strongly recommend trying out some used American Standard/Pro/Pro II, 2008 or later. If you can't try one out, a used one on Talkbass classifieds is usually a safe bet - I've had 0 bad experiences and somewhere around 10 or so bass purchases here.
For MIMs, I'd be inclined to stick with the newest Player II models.
Squier Class Vibe 60s are also a good bet - I have found them a little on the heavy side, but absolutely solid P basses.
One of my two PJs is a Charvel though, a 5-string - the split coil is a reverse split coil. If you're ok with that, these are the best bang for the buck PJs on the market - loaded with features and in the MIM Player price range. Much nicer necks.
