It’s the same way with Microsoft Surface line… I think it’s more so Google wanting to build hardware for their ecosystem.
Microsoft and Google desires to mimic what Apple is doing… Controlling the hardware and software experience, they both want to do the same for their customer base. I understand where you are coming from, but sometimes I think its a matter of the company itself… having a portfolio of hardware to show off.
But even from an ecosystem standpoint, Samsung blows Google away.
Phones - S22 Ultra over the Pixel 6 Pro easily.
Watch - No Pixel watch yet.
Tablet - S8 line over anything Google has ever produced
Earbuds - Several of the Samsung options are better than the Pixel Buds.
In my opinion, if you are interested in going all in on an ecosystem, you'll see the biggest benefit on the Apple side. But if you want to save money and you prefer android, going all in on Samsung is a smart choice. I dont think they've reached Apple levels yet, but they are making huge strides each year.
