Yes, I was a bit hard in my answer, because you hurted me with
........etc, etc, etc...........
The truth is that you braved me since replying my first post: this is a topic where OP required "suggestions" (do you know this term?) from each user, not debates, nor topic wars.
Reread the topic, reflect about and get out, you told enough.
Just because I pointed out that it is the Samsung S3 forum (in response to your ramblings about Samsung ROMs better compatibility with Samsung devices) does not imply the use of only stock ROMs and nowhere have I even suggested that.
By performance I assume you mean speed, which I have said nothing in my posts about - you are the only one to mention it.
As absolute speed versus battery life impact each other so much I deliberately did not mention it, choice of kernel and user config can massively affect both for stock and AOSP. If you mean functionality then give me stock based any day....
I DID suggest a ROM several posts back, if you'd bothered to read the first part of post #13. it was you who started the debate after I disagreed with you when you implied that AOSP was better in every respect calling stock derived ROMs 'almost useless' which is inaccurate and misleading to the OP.
I am not wasting anymore time on you, or taking this thread any further off-topic.
