We try not to say anyone is better than another here but here are 2 bad ass fully customized stock roms I'd suggest..
This is the one I've been using for like 2 months now
And here is another really good rom made by a really dedicated developer.
Don't know if you know but you can use any rom for the 3 carriers of our galaxy s4 with the snapdragon processor. Tmobile, the international gt i9505( not the i9500 that's the exynos processor, att
So I have all the threads for them favorited on my forum app (tapatalk). So I can see what's out there. All of them have different developers

I will look into them.
