Here's the story. My SD card got corrupted and I was previously running the AK2 firmware. I decided to pull off the switch to AKAIO to see how it went. Appearance: Well, obviously, the menu looks the same, but the insides are completely different. On AKAIO, I got hit with noticeabally more menu options than the AK2 menu. But the menus are kind of complicated - the dedicated cheat button in the AK2 firmware is gone in AKAIO. And I took me a couple weeks to realize saving my cheat file was the SELECT button, written in very tiny at the top of the menu. AK2 firmware - 8/10. Well placed menus and little clutter. AKAIO - 7/10. I got lost in it rather quickly, but gives more options than the AK2 firmware. The insides: The AKAIO firmware started with all the patches off, and the AK2 firmware starts with all the patches on. The AK2 patches get kind of annoying as each ROM has universal settings while in AKAIO the ROMs have specific patches for each ROM. AK2 firmware - 7/10. Well chosen defaults - but no specific ROM settings. AKAIO - 7.5/10. Face it - the defaults are badly chosen. But having specific ROM settings puts AKAIO at the top. The features/user interface: The AKAIO firmware is obviously larger developed than the official firmware, as the menu is bigger, 3 in 1 support, wifi updating, etc. The AK2 firmware is low on features but a bit more well organized than AKAIO. AKAIO had the stuff but was easy to get lost in, while the AK2 firmware didn't have much but was very well organized. AK2 firmware - 7/10. Like a clean office desk. AKAIO - 8.5/10. With Wifi updating and good 3 in 1 support, AKAIO gets the top but gets dragged down by confusing menus. So what can we conclude? After messing with the AK2 firmware and AKAIO for a few hours, it's pretty obvious that AKAIO is the winner with more plugins, wifi updating, etc. But the AK2 firmware is easier to work with. AK2 - For newbie users AKAIO - For advanced users. I'm betting I'm going to get flamed and crap after this.
