"I would definitely advise a inexperienced sub to avoid an inexperienced Dom."

That's a pretty sweeping statement. I would rate ability to connect emotionally as far more relevant than experience swinging a cane.

"inexperienced Doms generally lie about it"

Eh... well, I can't speak for any but myself I suppose. But I have to take issue with that. Plenty of veterans don't seem to have any problem bending the truth either.
