I cannot comment on the usefulness of the touch bar as I haven't actually used it, but based on other users' experience and various reviews, it seems it is from complete failure at worst, to marginally useful at best.
As for the other points you make:
- stronger wifi receiver. While technically true, you will never be able to tell the difference in actual usage.
- 2 fans (which would mean less thermal throttling?). True, although with the usage you describe, you are extremely unlikely to experience thermal throttling anyway.
- faster cpu 3.1 ghz. See combined answers to the other 2 points above.
Honestly, the difference in price vs the non-TB model is basically just for the TB itself and 2 extra ports. I personally don't think it's worth it, but others may like it.
