Confused about which company to join

I am a software engineer with approx 3 YOE. I have offers from two companies both of which have their own merits and demerits. I'm having a hard time deciding which company should I join. Mentioning the details of the companies and offer below:

Company A:

1. Public company (not profitable, but good revenue growth over the last two years)
2. Get to join an existing team and project to work on interesting distributed systems challenges
3. Salary: 60 LPA cash + 10 LPA RSUs (with annual refresher grants)
4. Fully remote, don't need to relocate
5. Career growth would be typical to that offered by a large startup (around 2000 employees)

Company B:

1. Private company, profitable, excellent revenue growth, planning to IPO in the next 3 years at a ~$10B valuation (which is reasonable considering their growth)
2. Get to be a founding engineer of a new team and work on a completely new project, involving very hard distributed systems challenges
3. Salary: 41 LPA cash + 3000 NSO units (will increase as I get promoted)
4. Hybrid, need to relocate to a different city
5. Excellent career growth opportunity as the project has a visibility at a senior executive level
