JellyBean vs Lillipop / Stock vs Custom



First of all, this is not a childish "versus" topic to flame fanboys spirits. I just need some technical understanding of some issues.
So... I've run four or five Lollipop 5.1.1 custom ROMs on my C5303, including CM, AICP, XenonHD, Mokee. All are great and fast and developers made a tremendous job. Not all of them are so friendly with Tangerine kernel (I need a custom kernel for increasing in-calls phone volume), per instance, Mokee hangs and struggle like hell. AICP works well with T-kernel, but with some issues (reported by users), when the device will freeze for a few seconds. XenonHD loves T-kernel - no problem at all!

Still, all of these fantastic custom ROMs , with or without custom kernel, are sluggish compared with stock 4.3 Sony ROM. I've made a nandroid backup in TWRP of my XenonHD - T-Kernel installation and installed Binomical SLIM 4.3 base don stock. Just for the heck of remembering the Sony UI, I intended to restore XenonHD soon after. I'm still on Binomical 4.3. Man, this is FAST! This is a blazing rocket compared with any of the Lollipop ROMs!

On Lollipop ROMs I've had ~ 300 MB free RAM, on stock 4.3 (OK, deodexed and slim) I only have 150 MB, but Sony's ROM is way faster and smoother. It really looks like I have a completely new device in my hand. How is this possible? Why? The hardware drivers? Is X-SP really not able to handle Lollipop in a decent manner?

XDA developers worked so hard to gave us the Lollipop ROMs, and I praise their work, but looks like X-SP best choice is still the old JellyBean 4.3. :rolleyes:
