[Noob question] Android update version by version or direct update ??

Hi friends,

I have this question for a long time. Currently I degraded from 5.1.1 to 4.4.4 ( .157).
So is it fine to flash the file prerooted firmware 5.1.1 ?? Or should I flash prerooted 5.0.1 and then prerooted 5.1.1 ?

Thanks in advance.
