Personally, I still encounter several bugs with the archinstall tool. Sometimes, it works flawlessly, and other times, it fails, requiring me to go through additional steps to identify the root cause of the error.
On the other hand, I haven’t encountered any such issues with ChrisTitus’s tool “yet”.
Some other people have had issues too with archinstall:

I don’t mean to offend you, but it’s better to just stick with the manual installation.
I know it’s overwhelming when getting started but this way you’ll make sure everything is working as intended.
