I think it’s not purely BT fault, not on Ubuntu 20.04, could also be Pulseaudio.
I’ve found Android more reliable for BT. It is just my Linux is a full laptop (keyboard, trackpad, multitasking) so is easier to do many things at once while Android is only good for 1 or 2 things at once.
The most reliable bluetooth + Linux product I’ve ever owned is Bose.
There’s always some risk with any product, so before purchase work up a test plan and on delivery test an item in the free return window, and no hesitance to return it.
You can’t avoid having to waste time with a product but you can avoid paying for something you don’t like.
