Indeed, I defer to your greater degree of experience. I probably should have prefaced my remark with "in my limited experience with senders", which was with only two VDO oil temp units. The variable readings I got from two senders on the same gauge were with one of them being of unknown history and dubious functionality-- dirty, discolored, tab broken off and a 18ga wire soldered in its place. Undoubtedly my faulty readings were the result of something other than the thermistor's resistance. If you say sensors are reliable, I take it as true. Though I think I would add the caveat that even something as simple as a thermistor based sensor can be buggered by a determined idiot, even if all he can do is mess up the mechanical connections.

Typical OEM gauges use far less accurate methods of displaying temperature. >

We're definitely in agreement there, as anyone who's ever taken apart one of those OEM gauges can attest.

Yeah, on those you'll definitely see more error just from the resulting parallax of moving your head around than you'd see from sensor variance.
