We used Cloudapp so far for recording and sharing videos with clients. As an Office365 customer, you can also use Microsoft Stream to directly screen record - but you can't share it with guests inside your tenant. Berrycast is a good alternative for that:
a) it integrates on the desktop and has very good hotkey controls already
b) I can see the teams integration to be very valuable, because it solves the MS Streams issue that you can'T share video in a team with guests. Ideally it is well built so that it automatically has view permissions granted for all authenticated users (and guests) on the team(s) that a video is shared to.
c) the encoder is ridiculously fast compared to Cloudapp. I have waited 10minutes+ for longer videos with cloudapp that Berrycast encoded in around a minute. Also the sharing is well implemented with the URL being generated before the upload is complete.

There also downsides:
a) the user management is not well implemented. There don't seem to be clear user roles and it is not clear to me, if someone that I invite can invite anyone, etc
b) it's unclear to me how videos are shared with users in the same "tenant" of berrycast. I currently assume that everyone just sees their own videos by default - but let's wait for the teams integration to judge on that.
c) There should be a way to bulk add users. We bought the unlimited users level - and I would like to simply import my colleagues in bulk
d) There isn't yet a bulk installer that I can rollout in the company (i.e. a MSI file that can be deployed through inTune, there is no guidance on how to actually deploy it in a larger team (support simply doesn't respond to this question)
e) The berrycast branding is a bit overwhelming, it would be nice to have a password protected sharing page with our company colors and logo tied to a subdomain.

So: A very good and fairly priced tool for solo or small teams - but to actually make use of the unlimited users approach, it still feels a bit clunky. Great value for money nonetheless.
