I really like Homasote better than foam, and have used it for almost 50 years on numerous layouts. The foam does not hold track nails or screws well. However, having said that, I am using foam on my next layout due to the weight of homosote. I am getting old, and carrying homosote to the basement is not going to work anymore. So foam is going under the track this time. I need to experiment with different types of track hold downs now. Folks seem to have good luck using foam, so we will give it a try this time.
