Hmm, Verizon had a hard time activating.

That may be true (likely a particular VZW agent issue, I bet), but the VZW version of the phone only has additional high frequency support, which is only relevant in a teeny-tiny number of places (like a set of blocks in certain cities, and even then things have to be pretty specific), it's more about VERY high-density usage, where these "towers" (not really the right term, but same principle, really more like Femtocell units) are present, dozens on a block even, say for a high-rise, or similar with a LOT of concurrent users.
It'd be unusual to have these areas not be covered by mid-band 5G as well and/or solid 4G/LTE, as well, almost unheard of, at this stage of deployment, since many users depend on 4G/LTE (3G just sunsetted over the past couple of years, for most US carriers anyway), it'll be quite a few years before 4G/LTE coverage starts to lag, IMO, based on 2G/3G history.
How VZW decides to connect to different signal-tower thresholds, based on relative signal strength vs bandwidth is their call, as part of their provisioning (and can change, periodically).
My P7Pro performs vastly better, in terms of signal strength/quality in a few areas I've tracked, than my OnePlus 9Pro that it replaced. My daughter has an iPhone 13, and honestly I can't think of a time that either of has noticed significantly better signal quality.
No question, some phones do a better job with antenna setups, or have a bit better chipsets, but at this end of the spectrum of phone quality, and current times, I'd be interested to see some sort of "survey comparison", something reviewers almost never do, for a whole variety of reasons...
