Control position - Totally subjective. Personally, I think the P3n has a better position and design for the shutter speed knob than the LX, and has a better location for the cable release socket. Does that make the P3n a better camera?
TTL flash - Way, Way, Way overrated, especially if you are a pro.

To each his own. I own both an MX and an LX, both of which are well maintained, and, to my subjective eyes and hands, there is a big difference. I do use TTL flash and off the film metering. The LX is my go to for low light film work because of the OTF metering and the finder layout with LED on the side. TTL flash is not just a pro feature. It makes the camera work with newer dedicated DSLR flashes like the AF540 and 360 without a lot of resetting. I've blown more than one shot with non-TTL bodies like the P5 by forgetting to set the AF540 from its PTTL/TTL default to Auto and then dial in adjustments from there.
I don't get the point about the P3N. If you find one of the advantages of the LX on another camera, or one thing you like better about another camera, it does not necessarily make that camera better as a whole. The P3N is not in the same quality league.
But, if you don't use the weather sealing (I don't either), or the interchangeable viewfinder, or find the camera feel more pleasing in the hand, or use the off the film metering, or use the TTL flash, or the sturdier winders/motor, or find the size (slightly larger than the MX) a better fit than the other M series, then you shouldn't spend the money for the LX. As I said, to each his own.
