I have compared against Bose, Sabbat e12, Anker Liberty Sound Core and the SoundPeats tws.
I started with the Bose because overall I have had pretty good luck with Bose bluetooth for my mobile stuff and I am a big fan of having the Multi-Pairing with my devices. However - the Bose were laggy on youtube and I watch a lot of YouTube so that was a no go... It was so bad, it was also instant no matter what I did on every connection. It was frustrating because they sounded the best out of the ones I tested.
I had connection issues with Sabbat...some weird stuff actually, like they were out of sync and then even connecting to the phone wasn't all that smooth, had to reset a couple times. I didn't appear to be the only one.
The Anker had drop outs - a couple in a short period of time, didn't care for sound or fit either but... dropouts.
The soundpeats were pretty good with connection in the short time I used them, they actually sound pretty good too but they don't stay in my ears at all so I didn't use them much. I haven't returned them yet if anyone wants to buy them! haha
That is my experience and sort of where I am coming from in my comments. Till something changes my mind I will only be interested in TWS that has this technology as it's a full solution of connectivity for whatever product it's needed in for TWS. So you don't have to depend on the headphone maker to reinvent the wheel and hope they get it right.
