Yes, very good to have EAD at least as you are in legal status. Think about all the Indian and Chinese nationals who are in line for a green card after H1B for 10+ years due to backlog. They only have EAD to make their presence and work in whatever company they work at legal. So even though TPS hasn't been approved, people who have TPS EAD are in good legal standing. I know some friends who don't have neither TPS nor EAD approved. I would not be worried if you have EAD approved. Hopefully everyone gets everything approved soon!
