Well, it surely is: it's worse, and not even by a narrow margin.
Low image quality, artifact compression, input lag, an arbitrary cap to resolution and framerate that may not match what a competent system is capable of.

Frankly there's absolutely no reason to even consider it as an option unless your machine simply struggles A LOT to keep up with the game.
You could somewhat made a half-assed argument about the possibility of "using it in some different place than your home/usual gaming spot", but then again what's a realistic scenario where someone would sit down to play a big-ass game like BG3 for extended periods of time, with low latency bandwidth readily available (that means a cabled connection) and NO computer at hand? Not impossible, but a fringe case for sure.

Funny thing, the aforementioned issues with Stadia are going to make this chain system even more flawed there. There's simply no realistic scenario where adding bad compression, bad image quality and more input lag to an already fairly clumsy control scheme is going to make it feel "completely fine", unless you are willing to lower your standards under sea level and play "make believe" to delude yourself into the idea you are having an optimal experience.
