If you don't have to use them - DON'T
You don't have to use them. They are S L O W to verify and you can't check in in the US unless they have verified your documents. So my advice is to NOT USE THEM unless you have to. Give them as long as you can to get their job done. My experience with Verifly and American was terrible. Verifly could not get to my documents and American had a 4 hour wait time to speak to an attendant.
