Video chat tool recommendations?

What's a good tool for live video chats?

My platforms: Android, Windows 10

No more than three connections needed -- no group calls.

No ads (I'm willing to pay), might consider free.

Good resolution, good controls (close-up, etc.)

So far, I'm leaning toward Skype on Windows, and starting to trial Skype on Android.

Skype or Webex. Stay the hell away from Zoom - no security on it whatsoever. An 8 year old can hack it.

That overwhelming quantity of security vulnerabilities in the app which has been developed since 2011 and has about 300 million users shows that its developers either don't know about secure software development https://www.ptsecurity.com/ww-en/ana...e-development/ and have never heard of SDL or deliberately ignore secure requirements.
