Strava vs FitBit on Pixel Watch

I use my Pixel Watch 2 for training, but stumble upon the fact that sync between Strava, FitBit and Fit is not ideal.
Thus, I have more or less decided to use Strava for my training session.
My question is, how will this affect the FitBit scores and activity level as well as the readiness indicator?

In most part I do not think it will if the watch is still monitoring heart rate 24 hours a day thus esnuring the heart rate data during exercising will still be recorded by Fitbit. And if you have Strava linked to Fitbit then exercise activities recorded on Strava should by synced to Fitbit app as well. The only information missing would be the GPS related data.

That is one of the issues -  Strava will not sync to Fitbit and very seldom the from Fitbit to Strava. I am frustrated by the lack of integration between the two platforms. I also understand that it is related to Fitbit, as Strava has a firm interface that they are offering to all other services. Thus Garmin, Polar, Amazfit and other sync and without "any" issues.

Syncing between Fitbit and Strava works fine in my case in both directions. I track my exercising activities with a Garmin watch, sync them to Strava and they would then appear on Fitbit app I have connected to Strava. But again, without the tracked GPS route.

Sounds awkward, no issues? What about other activity types than running?
