Both should be good enough for remote work.
There may be legitimate differences that make this harder for the US that aren’t simple failures, but you haven’t identified one.
Specifically the files are also hosted remotely but the local text buffers are synced in the background not every keystroke.
Choosing a shared environment is basically choosing to randomly give your development team a snow day. Maybe you’re okay with that tradeoff, but when it rains it pours… prod likely will go down when you can’t use the cloud dev machines.
Using AWS as an example (because that’s what I know), if Cloud 9 in us-east goes down and it’s not the entire service, I just launch from another region, do a git clone and keep moving.
It takes less than 2 minutes to bring up an environment if GCP’s offering is similar to AWS’s. I am assuming it will be.
