Default [Q] Schedulers

Hi and forgive my 'noobness' but do you guys think there's a significal difference in performance/battery if I use a different scheduler, because I googled a lot about the differences between all of them and I actually understand what all they do and their main advantages. Some people say that ROW feels quicker than deadline but Im not sure if its placebo. A guy in andrux-and-me(dot)blogspot(dot)com(dot)es/2014/05/io-schedulers-and-performance-2(dot)html compared/tested them so that's why I was wondering.
I always use the default scheduler in ElementalX (ROW I think) and never had any troubles but I also believe that Franco uses deadline so I was wondering what the experts here have to say.

Difference isn't too noticeable for most.

I actively add ignorant people to my ignore list.

I've done benchmarks with some schedulers at different buffer sizes, and other users have done way more extensive testing.

it is heavily device dependent and benchmarking does not exactly reflect real-life usage.

your best bet is to find one that works for you.

my two most common are row and fiops at 512 or 1024 buffer.

it all depends how personally you use your device. how you use it would show you which one to use. i use only deadline. it works perfectly for how i use my device.
