The performance depends on the number of items. The Set method should be the one recommended.

@OXiGEN Yep, either the browser implementation of Set has been improved, or it depends of the type of data. I should have written my arrays initialization in my answer :(

Turns out Set is much faster, especially as the records increase (for Numbers at least). See runnable testers at stackoverflow.com/a/66129415/2578125.

Thanks for this and putting the performance numbers in easy to understand ranked % figures. I was originally searching for Set based options because of simplicity. Given my datasets can get very large, performance is definitely a more important consideration!
