Having done that a couple of times during the last year, I don't really like it. The fact that it is recored makes obvious any flaw in delivery or hesitation. This leads to a long cycle of re-recording and re-editing that is very time consuming. Particularly grating is the occasional helicopter or lorry that goes by, resulting in yet another pass of recording and editing.
I also have to control everything about the environment (lightning, background, microphone and camera quality, etc), which is a pain compared to a conference organiser providing technical support.
So it is much more time-consuming to record the presentation compared to preparing it for live delivery.
I agree that pre-recording is better than live over video, for the reasons you mention (otherwise, there is nothing you can do regarding any stray helicopter or your router having a bad day).
I hate interacting in chat. Everything feels fake and wrong. People always need to pay attention to everything, lest they interrupt someone starting a sentence or trying to intervene (any latency is really bad in a vocal discussion). This is a bad imitation of chatting with other people over a beer.
The ability to re-record is a mixed blessing: it is a time sink and it is very difficult to be satisfied with the result if you are even mildly perfectionist. It would be better if we had access to professionals to record and edit talks, but we haven't.
I was really comparing live over video to pre-recorded over video. I agree it's easier in many ways in person and that's my preference. (That said, my videos on YouTube are watched by far more people than in-person unless I'm giving a keynote.)
That said, it's gotten easier over the past year. My office is pretty much set up as a studio now with lighting, mikes, camera and so forth. And I've learned things like better eye discipline. I've also learned that, sure, I should do a retake if I really flub something (or, umm, forgot to hit the record button). But for anything longer than a very short clip, it doesn't need to be perfect.
But, then, this is one of the things I do for a living so it's been worth the time and money to get things right.
