I'm a little bit confused about the grammar used in the following two sentences:
1.) (...) looking back at it, it was the best decision I have ever made 2.) (...) looking back at it, it was the best decision I had ever made
I personally would choose the former one simply due to the reason that it sounds more natural to me! However, I have heard using native speakers (England) the second form as well! I'm not sure now if that's just bad grammar on their part or if it's actually grammatically correct!
Thank you in advance
