its hard to say whether manilla or titanium is better. personally the way i feel after flashing many roms, is that manilla is more user friendly to get customized and more familiar to a stock rom user, but is more bulky and less finger friendly. a 6.5 rom with titanium only is much more finger friendly (i never even pull out my stylus anymore unless on browsing the web), its more lightweight and seems to me to run smoother, and is more sleek and eye appealing. The first 6.5 rom i flashed i only used for about 20 minutes before i decided i didnt like titanium and went back to flashing 6.1 roms with manilla. after playing with manilla for a while, I decided to give titanium another go, and flashed a 6.5 rom. I havent gone back to manilla yet because im a bit more used to titanium, and more comfortable with modding it. it just takes time to get used to, but i think its safe to say i wont touch 6.1 again at this point.
