I hacked the firmware on my psp a long time ago, and since then its sat on the shelf. I am thinking of tinkering around with it again, but I am a little overwhelmed with all the choices now.

1- I couldnt find a thread with the differences between the current firmwares. Pros/cons of each and which I should go for. What functionality they contain over each other

2- I am currently flashed to the dark_alex 3.10 OE-A. Can I do an update to an updated alternative Firmware directly? Or do I have to do a sidestep/downgrade? Would prefer to not have to make a Pandora since I dont have another battery and dont feel like buying another one.
