Pros of resigning: Maybe maintain some relationships? Maybe HR will respond to future reference requests with 'you resigned' rather than "you did not work out". Maybe you can negotiate some severance pay?

Pros of being fired: Maybe eligible for unemployment insurance. Maybe it will take ages for them to do it, so you'll lose less income.

Apart from the considerations above, it's worth reflecting on the experience and what you might have done differently. Even if only 1% of the responsibility lies with you, there may be some valuable lessons. Your perspective on this situation may change a year from now, or 5 years from now.

There are stressful work situations from 10-20 years ago, where my perspective today is totally different from how I saw things at the time. And in some cases my perspective evolved several times in the intervening years.
