Nib wear issue: which models of tablets/pens are affected?

I'm looking at current and slightly old models of the traditional pen tablets. I've found posts asking some of the same questions I'm asking here, but no clear answers, e.g. [this one](https://old.reddit.com/r/wacom/comments/9shwol/intuos_pro_nib_wear/?ref=share&ref_source=link). Note: All model numbers below are for medium sized versions.

I understand that the current Intuos Pro (PTH-660) with the Pro Pen 2 suffers from rapid nib wear. It's still unclear to me whether the alternate "smooth" surface makes much of an improvement. Has anyone tried it?

Does the previous Intuos Pro (PTH-651) with the original Pro Pen suffer from the same issue? If so, is it better/worse/the same? What about the current Intuos non-pro (CTL-6100) or the previous Pen and Touch (CTH-690)?

I've never owned a tablet before, and I'm also not a professional, so having to buy a never-ending stream of pen nibs is a factor that would push me towards older/cheaper models.
