It's what I've used for years and it's entirely fine for me.

For a long time I installed iterm2 because "that's what you do" but one day I realized I was suffering a little wasted disk space, slightly slower start-up, and slightly worse input latency, for... no reason, because I didn't do anything with it that Terminal.app couldn't do.

25 years on unixy operating systems. Spend tons of time in the terminal.
