Learning with native / non native speakers

It’s a controversial topic. Is it beneficial to practise a second language with non-native speakers or counterproductive? I’d love to have more speaking opportunities with people from English speaking countries. Unfortunately, it’s not always possible and therefore, I don’t have a problem speaking with other learners.
My weakness is grammar and I noticed making more and more mistakes. Even worse, I’m getting used to them and don’t recognise them. I’m always thankful for conversing with «native» English speakers, especially when they correct me.
