This is something that is more in my wheelhouse coming over from television to the internet, so I am a bit of a gear nerd.
I think it really comes down to what you are looking to do and what your backdrop is most of the time. Is portability the biggest issue? Is it a lot of run and gun? Are you setting up in stationary places?
For me, I think audio is the biggest thing that people miss out on when they are doing that quick video. I have countless mics and tools that I have demo'd (not on camera, maybe some point I will start doing more tech reviews, but need to build my count) and other various camera. At this point, I am trying out the media mod for the GoPro 9 to see how much I like that, but I have a feeling that the audio still might not be great, especially since I do a lot of two-person videos in the field (well, did pre-COVID).
I just got the Elgato Cam Link 4k and will tie that into my Sony PXW-X70 and see how that works with a livestream set-up... but for now, I am hoping that my GoPro 9 might be the answer that I have been looking for in terms of the run and gun mode. One thing that I will say about the GoPro in the sample runs I have done with it is that low light takes a second for the camera to adjust to, so you really can't throw enough light at it.
I am not a fan of using DSLR cameras for vlogging (I have a Canon 90D right now as well as a Blackmagic 6K pocket cinema camera that I have not had time to set up). I guess coming over from television, I still am going to be one of those holdouts that likes using video cameras for instances like that.
I guess there are a ton of questions that I could ask you to try and help narrow things down... seeing your range being in the 200 pounds neighborhood helps, but generally knowing what the primary use is going to be will help me try and narrow some things down for you.
(And yes, I hate using my phone for anything of consequence, but I am just stuck in my ways).
Let me know if there is anything else I can answer, I certainly don't have all of the answers but I have strong opinions.
