I've got Supreme Magicka which lets me put a cap on the Chameleon percentage at what ever number I want. Not as complex a solution as AV but it is simple to use and gets the job done.
As I recall, Elys is really simple to install and use, just paste a single .dll file into the OBSE plugins folder. I suppose if you want a more complex solution, AV would be fine, but if you just want somethign simple that uncaps the attributes and most fo the skills that benefit from an uncap, then Elys works fine.
But I tend to like some of the older mods more than some of the newer fancier options. Like Galerions unarmored, I use the original version, rather than the new version because I did not want some of the bells and wistles the newer version added. I hate to say it since I am always complaining about the "simplification" of the series, but sometimes when it comes to mods, I prefer a simple solution to a solution that adds complexity than I need.
