Is Google worth ditching my new employer only 6 months in?

I passed the Google interview almost half a year ago but it took until today to have a team match. I am obviously very happy but having a lot of 2nd thoughts.

The issue is that I have recently started at another big tech (whose name based of a forest in South America) because the Google team matching was hopeless. I am considering the pros and cons and would appreciate everyone's input

Additional context:I am running out of my open work visa soon (non-US based). I have to rely on my employer to sponsor my closed work visa (binding) after it ends until I finalize my permanent status. Since switching jobs on the binding visa is much harder, it would effective make my choice a commitment at least 3-4 years long

Current team:
Pros:
- reasonably chill
- teammates are genuinely nice and helpful
- most people got promoted within 2 years or so

Cons:
- The work is very boring and tiring - The team future is unclear as its scope gets smaller every week. The org is known for layoffs - The new manager is not really helpful in roadmapping and getting scope for promotions. - 5 days RTO

New team (Google):
Pros:
- 3 days RTO
- Work sounds very interesting to me and it is exactly the area I want to learn
- The Google culture is known to be good
- Somewhat better brand name?

Cons:
- unclear actual state of the team
- promotions is longer on average (around 3 years?) - in addition, I will forgo my 6 months work, so the total extra time to promotion would be 1.5-2 years - bad reputation of jop hopping
