I find a lot of folks seem to ignore usability in this as well. These things are pretty close to each other on sound quality, but UI, playlist support, Eq and things like android are vastly different.
Since I write software to sync these things to a Mac I own a LOT of Daps.
Ak100 thru 380 suck on Macs.
Ask Jr UI is slow.
FiiO UI sucks but everything else is great.
Sony Nwzx2 can only mount one storage area at a time to sync, doesn't support balance adjustment but runs...
