Each to their own. I'm childless and I was fine with that, but now nearing my 40's, I'm having pangs... and I would dearly love kids. Unfortunately I have some chronic health issues that I would rather have a lot better before I take the plunge because any kids I have, I want them to have the best, healthiest life I can give them. But I think the important thing is, there's no 'better'. Obviously it's better for people who are incompetent, abusive, who have no ability to look after themselves properly to never have kids. But for the rest of us, it's important to respect personal choices. :)
