The benefit of direct is effort/reward. Your hit rate is lower, but you get higher quality interactions with far less effort. Direct produces far fewer flakes as well.

With that said, there are a TON of people who have had success with direct... including most people on this forum and literally every guy I've ever coached. Generally once guys get success with going direct, they never go back to indirect. I don't even teach indirect day game and haven't in about three years because it feels completely pointless.

You still haven't answered if you've laid any of these girls, or even gotten them out on dates. You obviously can get phone numbers. But phone numbers are very easy to get. If you genuinely want help and advice, then you need to be honest about what you're having problems with.
