Depends on what you're building. Raspberry Pi's are hard to obtain, much more expensive, overkill for tons of tasks, and involve learning or already knowing a bunch of linux / sysadmin knowledge. In my experience, arduinos get picked over ESP32s mostly because someone's already done what you want with an arduino so you can leverage existing code/projects. Not every project needs wifi, or 240mhz, or 32bits. And in those cases, the beaten path is the best choice. That said, yeah, esp32 gets picked a lot even when the wifi isn't needed, because it's starting to be the beaten path.
