Thought I'd throw my 2 cents in. My side hustle is freelance digital artist and I've been using Poser for about 15 years, and Daz Studio for about 5. So if anyone has any questions feel free to ask.
To answer your question, with a little Practice Face Gen works really well with Daz Studio. I often get requests for self portraits, so I created a googledrive folder to show clients my digital clones. https://drive.google.com/drive/folders/1jyVCOgqu3CMeecj6TYPEyDicVaKOKF2P?usp=sharing . All those characters were made using FaceGen, Genesis 3 (Male and Female) and a little photoshop.
and for anyone who doesn't want to use the googledrive link, you I have some facegen examples on my website. RLPattersonART.com.

What is the best face program to use with DAZ? Then you can make anyone or very close to it. I've heard of FaceGen and feedback would be great for anyone with experience with it. Here is another one. This one looks promising.
I also hear good things about Keentools with Blender for faces.
