I just would like to know if there was some analysis about how SFOS behaves compared to similar mobile OSes, I mean iOS
Disclaimer: My knowledge of iOS is not firsthand and likely outdated. Clarifications from more knowledgeable individuals are welcome.

and BB10.x which are both *nix and native (AFAIK, Android runs Dalvik/Art and WP runs .Net). And if this comparison was completed, what are its results?

Regarding iOS, there is a very detailed blogpost explaining the five different states an iOS app can have.
This information is more than 3 year old but I guess it's still valid.

One particular problem to look out for is that because of the way Ubuntu Touch currently handles applications CuteSpotify has to be kept in the foreground and the phone has to be kept switched on for music to play (otherwise the application gets suspended). Approaches for handling applications that need to keep running are currently being debated, so hopefully that won’t be the case in future version of Ubuntu Touch.

It remains much the same. Ongoing discussion. Pretty much makes Gps programs such as track recorders useless, as who wants the screen on for that use case?
That said, it is WIP and issues are openly discussed. Small team, so progress is slow.
I enjoy the MX4, mostly for the browsing (this was a major issue on the n900 in the end for me) and the camera is very good. Otherwise the n900 keeps my heart.

moaarrr ram seems to fix the issue since i never have the over zealous OOM kicking in on the nexus 5 SFOS, but that doesnt mean other issues dont hinder performance,

You cannot be talking about Jollla, as GPS tracking with it works perfectly and I use it several times a week, both bicycling and hiking in woods.
My longest tracks are over 3h in length, logging coordinates every second and I have never lost points...

At this point it's a slightly bizarre state of affairs where a Linux company is being out-multitasked by even iOS and Windows Phone 7.
Some months ago, when Jolla changed the behaviour of Sailfish in case of a lack of memory, there were a lot of discussions here and on TJC.
I just would like to know if there was some analysis about how SFOS behaves compared to similar mobile OSes, I mean iOS and BB10.x which are both *nix and native (AFAIK, Android runs Dalvik/Art and WP runs .Net). And if this comparison was completed, what are its results?
A simple question for my own culture and understanding.
Thanks.
