I find that much scarier to do personally since it seems a lot more likely to screw up other stuff on your machine, whereas with pyenv it's all self-contained in the venv. Also using apt packages tends to install a pretty old version.
No, installing a package with apt is not more likely to screw up your machine than installing it manually. Moreover, you seem to be completely fine using the apt-installed CPython, while you think PyPy needs to be installed manually.
I use pyenv myself, but that is beside the point. The two examples above are using different strategies to install python3 versus pypy. A valid comparison would use a package manager for both or pyenv for both.
