    A new filesystem shoot-out in 4.21 would be nice.

    Except it doesn't because F2FS runs on block-presented devices while JFFS2 runs on raw flash. It's really hard to compare them by their extra features if there are designed for a totally different cases.

    Benefits should be less writes to the underlying flash. But SSDs have their own, very sophisticated algorithms to compensate those along with a lot Ram

    F2fs is a good fit for eMMC storage (phones, embedded), where it should provide better performance and lifetime. It competes more with JFFS2 and other logbased filesystem than a ext4 which is journalbased.
    (Tha said I would not mind comparisons on SSD, particularly in terms of how much actual data is written with different fs)

    Edit: I see that it is faster in some (synthetic or database-oriented) benchmarks, but also that it isn’t well-supported by gparted, and it is impossible to shrink f2fs partitions.

    Phoronix: F2FS Gets More Fixes In Linux 4.21 With The File-System Now Supported By Google's Pixel

    The Flash-Friendly File-System (F2FS) has some new features for the current Linux 4.21 development cycle but it's mostly fixes stemming from increased testing with Google now supporting this flash-focused file-system for their Pixel device line-up...
