PLB or Spot Gen 3 in 2020?

I've never carried a PLB, EPIRB, Spot, InReach, etc. However, as I'm walking with my kids more often, and they are getting more capable, and for the sake of my wife's sanity even when the kids are not with me, I'm thinking that I should start doing so.
I'm more than happy using my iPhone as a GPS, so I don't feel the need to combine a mapping GPS with an emergency device (ie, InReach). They are expensive! ...and would just duplicate mapping GPS functionality I already have (and from what I've seen of hand-held GPS units, their mapping GPS software is generally terrible! Which is odd for a device that (in many cases) has no other purpose.
However, having a PLB without the ability to send out OK messages, and let others track me seems like a bit of a waste of money (unless you actually do need to get rescued of course), so I'd prefer something like a SPOT that will be of some use whether I ever need rescuing or not.
Who here uses a Spot 3? Are you happy with it? I've read of problems with Spots and their satellite coverage from a couple of years ago. Has this improved at all?
Is $219 for a Spot 3 a good deal?
Can you download your tracks later on as GPX (or other) files?
Please treat me as a complete ignoramus when it comes to Spots and similar, as I've never really looked into this before and I really do know nothing.
Please tell me anything that you think may be useful for me to know.
I suppose the main downside is the monthly subscription fee (equates to about AUD$250 a year, I think?). This is the one issue that may turn me off, and point me to a plain old PLB instead.
