I just moved a project from pipenv to poetry at work. My biggest issue with pipenv is that you can't selectively upgrade dependencies. Trying to `pipenv update xyz` basically blows away your lockfile and updates everything. There's a command line flag to be more selective but it doesn't work. I found an open GitHub issue about it that's years old.

Poetry by contrast works pretty much like any modern dependency system you'd be familiar with from another language like cargo, npm, or hex.
