Pokemon Go's account own doesn't work. Even if you manage to create that account, it won't log you in. With Google account it works as expected. I tried to create two Pokemon Go accounts, gave up and created a Pokemon Go only Google account for child's playing. It has worked a few years.

When did you have this issue? My account is tied to my Google account because on launch the Go servers were completely inundated and the account creation was just constantly failing but using a Google account allowed you to skip that step and start playing.

This was the first month of Pokemon Go years ago. I haven't heard of it being an issue lately but I also haven't needed to create an account in a very long time.

I think the first time was around the spring 2017. I could create an account, use the credentials to log in, but trying on several days the game never started. There was some "please wait" kind of screen and waiting for hours didn't help. With a Google account things worked right away.

And a bit over a year the same thing happened. New Pokemon Go account -> log in -> no game. With Google account has been working since.

So, my experience is two tries in the span of two years it did not work.

Pokemon Trainer Club accounts (what you thing of as "Pokémon Go accounts", even though they're used for other Pokémon services) in the past were more buggy than Google accounts, but for at least the past two years I have had no more trouble with my account than my friends who have Google accounts. Additionally, they created a feature where you can link Google/FB to your PTC login so if it does go down in the future you can log in with those other services if you wish.
