It doesn't really matter. You can do either. I don't use the intext link very often, just because I think it has a better chance of taking readers away sooner. I do use it on occasion, though. Especially when I have several hubs that are related but don't want to have a huge link capsule at the end.
A link capsule placed near the end of the hub adds a nice little something I think and is a great way to get readers to your other hubs.
