I use the DJI mobile I have the OSMO as well. Either works but I prefer the mobile as that way it’s your phone doing the work versus the OSMO Camera

It works great and I use it to record a lot of content for clients.

In addition I have a full camera gimbal. But I would recommend going with the dji mobile to start and then move up from there

The plastic parts on the II are no big deal it will still work great for what you want to do and to learn on
