Same experience here -- got back into dev earlier this year and decided to go with Python 3 everywhere. The only libraries I've needed that were Python 2 only were ones that weren't being maintained anyways. It's been a pretty good recency filter for me. I know that wasn't the case when Python 3 was younger, but the ecosystem is pretty dang good today.
As a Python dev, I (and all the other Python devs I know) were just waiting for (and helping) libraries to start working with 3 before we can switch over. These days, all my new projects are in 3, 2 is pretty much for legacy code only.
