Both of the WWVB clocks I've owned have been very fickle about how they're placed because RF be that way sometimes, and Colorado isn't exactly nearby to my location in Ohio.
The first manufactured GPS clock I owned (as in: switch it on and time is shown on a dedicated display) was in a 2007 Honda.
But a firmware bug ruined that clock: https://didhondafixtheclocks.com/
And even after it began displaying the right time again, it had the wrong date. It was offset by years and years, which was OK-ish, but also by several months.
Having the date offset by months caused the HVAC to behave in strange incurable ways because it expected the sun to be in positions where it was not.
But NTP? NTP has never been fickle for me, even in the intermittently-connected dialup days I experienced ~30 years ago: If I can get to the network occasionally, then I can connect to a few NTP servers and keep a local clock reasonably-accurate.
NTP has been resolutely awesome for me.
On the one hand, some sloppy GPS units fail on a 20 year schedule. On the other hand, a bunch of things using NTP are going to fail in about ten years. (2036 rather than 2038 because reasons)
The WWVB clocks are around the AM band, which means they carry a great distance despite their lower transmission power, but only at nighttime. Ohio is nothing; the signal needs to make it to the southern reaches of Florida.
