I consider all emergency communication systems to be essentially obsolete except full bandwidth satellite two-way communication systems. I get that two-way radio is also a lifelong and well established hobby, but that doesn't automatically make it a solid back-country emergency comm system ... in fact it's anything but.
Any two-way radio set-up has distance and/or "who's listening" limitations (think Canyonlands Needles District which has massive swaths of land in which no radio signal exists).
Simple In-Reach type communicators lack the ability to pass high bandwidth information in either direction, and both are also quickly being surpassed in terms of massive numbers of available satellites by StarLink.
The only exception I make to the above is for an expensive, high quality, dedicated emergency beacon (not an In-Reach texting device with a "button" that sends signal to a commercial entity).
I'm not a remote hiker, so I personally can do without an emergency beacon, but if your sole purpose is to send out an emergency message from a remote location only accessible on foot or you'll die in half an hour, then a true emergency beacon is your only real answer.
Because I'm not a remote hiker, my communication device of choice for everything from simple or complex emergencies to general communications is the StarLink Mini.
The Mini does it all at full bandwidth, from basic text, up to high speed two-way live video. A single StarLink Mini will also support multiple devices in your travel party simultaneously, from cell phones to iPads and laptops.
Direct Satellite to Cell is already here (no StarLink required), although it's text only at this point (and therefore no better than an In-Reach), but Sat-to-Cell will eventually replace StarLink completely - and will become the ultimate safety device for all travellers, be they remote or mainline.
I personally believe that hanging on to "old" technology in the realm of personal safety is not a wise choice, especially those hanging on to various forms of two-way-radio comms. If any subject is worthy of staying abreast of the very latest in technology, it's your (or your families) personal safety.
Of course too, anything is far better than nothing at all, although your choice of "anything" should be made as if your life depends on it, which it may someday!
