OS's ranked by functionality

[SwordfishII]

I would prefer to see sxmo in this list and my vote is for same.
SXMO - Pretty smooth. Already using it as daily driver.
-- Battery lasts for 7 hrs with new screenlock dev code
-- New UI changes are pretty cool ( no need to worry about buttons wearing out)
-- Rear and front camera works
-- latest app menu supports many applications
-- surf which is lightweight is good for browsing
-- foxtrotgps for navigation
--  youtube video and audio via mpv
-- calls and sms work (customized the code to use AT commands to make this work)
sxmo_devel has all these improvements from previous release
Thanks to all the developers involved.

I have also tried other os  - UB,mobian,arch and manjaro

I assume sxmo is debian based? What DE?
