As with all technological transitions, things will be messy in the beginning and eventually ubiquitous. In the meantime, the question over the past couple of product cycles has been, should I choose a device based on 5G? For most use cases, the answer has been an emphatic no. For the current/upcoming product cycle, the answer will be more of a definite maybe. By this time next year, it will no longer be a question, as it will be standard issue on nearly all new models. You'll get 5G whether you want it or not.
For the most part, the 5G networks still have massive holes, and for the devices themselves the 5G modem has been a power drain.
And to add to the confusion, there are multiple flavors of 5G service, each of which has differing levels of improvement over 4G LTE. The hype over 5G largely centers on the mmWave variant. That type of 5G is blazing fast and a huge uptick by multiples over the lastest LTE service. Great! Problem is that mmWave requires a much higher tower density, and is more susceptible to interference from buildings, land masses, and other large objects. Rural and many suburban locations need not apply.
Verizon has so far deployed only mmWave for its 5G service. That's why they can advertise that they have the fastest 5G service (by a wide margin). But, good luck getting a 5G signal outside of the densest areas of large cities.
Which leaves the lower frequency sub-6 5G service, which is vast majority of "5G" service. The sub-6 service builds on LTE, but you can't really call it LTE+ since it requires a 5G modem. Because it uses lower frequencies, the low band and mid band 5G service has longer range and is less susceptible to interference from buildings and large objects. But, it's also way slower than mmWave 5G, and recent tests done by both PCMag and the Washington Post found that low band and mid band 5G service is only a modest improvement over existing LTE service, and in some cases is actually
slower than LTE.
After a decade of testing 3G and 4G wireless networks, this year we drove around 26 US cities amidst a pandemic to determine whether 5G is ready for prime time. Find out which carrier's network is fastest where you live, and whether it's time to upgrade.

We speed tested 5G phones against 4G ones. America’s new nationwide 5G networks weren’t much faster — and in some places they were slower.

Further confusing things, AT&T has gone as far as labeling their LTE-A service as "5G Evolution". This is reminiscent of how some carriers called HSPA+ service as "4G" while detractors said that HSPA+ was really an extension of 3G. This is inevitable during a transition, so buyer beware.
If you're looking to get one of the upcoming iPhone 12 models, it will come with 5G. To some extent, it will futureproof the device as 5G becomes more commonplace in the upcoming years. However, if the rumors that only the top of the line iPhone 12 will support mmWave 5G turn out to be true, then that means the majority of the iPhone 12 models will be limited to the gimped 5G and won't ever support the fastest 5G speeds. That all adds up to compromises now, and a shorter shelf life over the long run.
Inevitably, the 5G modems will get better, cost less, and likely use less battery than what's currently available. This is the problem anytime you adopt a new standard during the early transitional period -- you'll pay a lot for something that will be more expensive and less futureproof than something that will become available in a relatively short time.
