Which ecosystem do you choose based on browser and services: Google or Microsoft?

I'm having a dilemma choosing a browser. I have a Windows 11 PC that I use 90% for the internet, gaming, and work. I have a Google Pixel 9 Pro, Pixel Watch 3, and an Acer Chromebook (as a backup computer when I don't feel like sitting at my desk, which I rarely use). This is the hardware I use for the remaining 10% of my "digital life": calls, texts, and the internet.

The bottom line is that Edge and Chrome are very good, and both meet my expectations and requirements (except for privacy). I'd like to use the same ecosystem, but Microsoft doesn't have its own operating system on mobile devices, and Google doesn't have a true operating system on high-performance PCs. Now I'm wondering which browser to choose so I can adapt one of the systems to the right ecosystem. It's true that I'm more immersed in the Google ecosystem, but migrating isn't a big deal for me. I was considering using Edge on my PC and Chrome on my smartphone, and syncing bookmarks and passwords with external add-ons, but I'm not sure if that will work because I'll have to switch between different interfaces.

I'm not really interested in which browser you would recommend, but rather in how you dealt with this dilemma?
