[Sony Xperia T, TL, TX, V] peter-k:
Short version:

Revelation is a deoxed and slighly feature upgraded 4.12. They both work pretty similar. Odexing makes the factory 4.12 slightly more smoother running. Pure-X and 4.3 look pretty much the same but I prefer Pure-X. I did not see the bugs that 4.3 has. A great work.

Long version:

4.12 and Revelation are pretty comparable in terms of usage, memory consumption and battery. The difference is Revelation comes with a few upgrade bits, such as the quick toggles. 4.12 in stock configuration is bland by nowadays standard. I brought it to 270 mb foot-print trimmed down. This leaves plenty memory room for user activities. The 4.12 stock odexing makes a difference, it makes 4.12 running sleek and smooth if set up well, and not endless numbers of 3. party apps are loaded. It is almost lag-free. Lags are present with deodexed versions and if several 3. party programs are loaded. Revelation runs at least similar stabil, but my feeling is it would benefit from odexed core to make it run even smoother.

Pure-X Blaster and 4.3 make the other group. Both have the white user interface which I prefer. Pure-X has 90 % of the features of 4.3. 4.3 has some refined corners in the user interface, but on the first look I'd not be able to divide them both. Both come in factory condition with a very similar memory foot-print. The difference is that Pure-X can be trimmed down easier to memory foot-print of around 340 mb, to me worthwhile pay for it's benefits and features. For example, there is a set of quick toggles similar to 4.3 (slightly buggy, but once set-up it's working all right).

Both with 4.3 and Pure-X the phone tends to run hotter. 4.3 has slower GPS and Wifi connection pick-up according to my my experience. Also - at least on my phone - after waking up it has sort of half a second hesitation, while Pure-X, 4.12 and Revelation are instantly there, and GPS and Wifi reconnection are faster.

As for odexed 4.3 and your de-odex "Simple is Perfect" ROM, they behave very much the same. In opposite to 4.12 I did not perceive any difference in handling things, or memory management, or smoothness from odexed to non-odexed.

I was impressed by how much you managed to trim down the ROM without hampering the relevant functional aspects. You must have invested a lot of trial and error time into it. I tried very hard but I still ended up with abt 100 mb bigger CWM size. The resulting smaller memory foot-print it seems gives the device a bit more breathing room to work properly without lags. So for those who must have 4.3 this probably is an attractive choice.

But what's wrong with 4.3? Watching for a while the memory usage with AT's Task Manager, I am surprised as how much "active" 4.3 is in the background. Things keep moving up and down constantly. What I mean is the memory bar is wildly moving up and down, and the programs memory consumption keeps on changing all the time. The older versions and in particular 4.12 and Revelation look more "qualm". Slow connection to Wifi and GPS and the slow "wake-up' effect are hampering my user experience. The heat development on the rear side is significant at times. This comes together with the bugs debated on XDA. Speaking straight like we Germans usually do: 4.3 ist ein Schuss in den Ofen. I am in line with White Neo, nice UI - but not nice under the hood.
