You're making the right decisions based on your experience coupled with what your ears like. If you trust your hearing and have the experience to tell whether a line recorded in harsh conditions will be OK or will have to be ADRed, you're automatically (probably) making the right decisions. After a few years that feeling is in your guts.
And if you can make a location sound good with the equipment that you're comfortable working with, then hooray!
Some people just prefer Schoeps over Röde based on THEIR experience. They're confident that they can make the right decisions based on their hearing with the right mics, lavs, txs, preamps and (hopefully) boom operators. They probably could get real good results with lesser gear, but they're have to relearn that new equipment and that takes focus and concentration, and as you know, those are two very precious assets on set that has to be deployed very carefully.
Looking at numbers... I don't really see it that way in this community of mixers for film and TV, although in music and PA I can reconize it. Several people here use Zaxcom txs and txs which sound amazing and are spectacular tech and feature wise, but the sample rate of the system is actually 32khz if I'm not mistaken. That's just one example. I know of many rerecording mixers and sound designers who use Zoom or other small handy recorders for quick FX recordings...
And yes, a sound person on set not reading in the general feeling on set (as you say a crying scene for example and they bluntly go "go again there was a car") is just... Sad. I've had that experience several times with mixers as a boom operator, and it's really hard on the whole team. To not just let go that time.. Then that person probably just thinks too hard or is very hard on him/herself..
