Talked to two pilots recently that have both used aerocrew. They both stated aerocrew has the dl prep nailed and was excellent for their delta interviews.

Can't go wrong with either from what I've been told. I will say though I have heard for years from so many that emerald coast has been top notch. I've actually decided I will go with aerocrew when I get the invite. I'm local to ATL and would be much easier than commuting to ECP. Just depends on what works best for you.

Again this is information from several that have used both. My understanding is they are both very good.
