Excelent iniciative Xerxin! This forum was needing it. I was going to do something similar when I had some free time (hopely I dont need anymore :P ).
But I totally agree with Nebouse. Legacy Xperia is actually the best 4.2.2 ROM for our devices. It should be on the list.
Other thing that you could consider was to have not only when it was released but when it was last updated (personally I consider this factor much more relevant).
Best regards and keep the good work
