I have not tried Updraft lately, ditched it for couple years ago as it was giving me a headache, it may be that it has been better with time as you state.
I'm at the point now that I don't see any reason for using any plugin when doing it without is as just simple and quick as with plugin, only that I don't need to spend extra time on doing it again those times errors come up, if I get error in 1 of 10 times I transfer sites it's in my head 1 time too much and wasted time
Anyhow, there is no wright or wrong way of doing it, if plugin is your preferred solution so just keep using it, I was just offering another solution that is quick and safe and that I'm happy with
