You summed up my own experience with Nettar pretty nicely (I also recommended it in Post No. 10). The only thing I truly miss is a rangefinder with that camera, everything else can be adjusted to. Okay, I can also adjust to not using a rangefinder, but I miss focus more often than not. And Novar is not that bad after f/8.
I find it’s remarkably precise to judge distances with your eyes if you train yourself.
The key is to have a meter stick to look at daily (or foot if that’s how you roll) and get real familiar with exactly how long that is.
Then imagine it laid out end to end a number of times away from you to your subject.
Your judgement will get less precise the further away you get. But your DoF of sharp, will also get comparatively much deeper.
Then you’ll be able to guess distances within a margin of 10 cm or so, for near field.
That’s a skill that will come in handy a lot in photography and life in general.
That said, a rangefinder can be nice.
They come in a myriad of types from old to new laser ones.
I much prefer external rangefinders.
What they lack in overall compactness, they more than make up for in being far more user serviceable and potentially precise than build in ones.
I can easily take apart, clean and adjust a Telex or Precisa RF, without risking the whole camera.
For real close focus for subjects within a meter or two , just bring measuring tape.
It’s more precise and fast than fiddling with a rangefinder anyway.
Using closeup lenses (which I highly recommend playing around with) your
need a measuring tape anyway.
