Marmite. Some are all for it. Some think it's a waste of time. For something like Photoshop or Premiere (or rather FCPx) I can see some use but for what you're describing I see nothing that couldn't be achieved with some judicious use of the command key.
I don't know tbh - what does the touchbar bring to the party, or rather what do you lose without it?
I'd kind of assumed that I would get one with it as I presume that's the new standard.
