There's a lot of ways to play games. There's a lot of ways to interact.
Lots of good answers, but you'll learn the most from asking the person you play with.
I played TF2 since the orange box came out in the mid 2000s. When I found a great clan, I voiced with my small and intimate group. Time with them was life giving. Outside that, I texted and used the team commands instead.
After years of hiatus and the clan fading, I disabled voice altogether in the game when i've played recently. Gamers can be unpleasant and it's only become worse over the years. Especially towards females. Nah. I'm not interested in talking with immature children. I like pwning quietly without assturds being their unpleasant selves in my ears holes. In fact, I haven't used voice in a long, long while.
Ironically, I hate texting and use speech to text nearly all the time. So I'm still voicing, but not directly. 🙃
