Yes, the SimonK firmware is specifically designed for multicopters and should improve stability. The reason there is so much discussion about the SiLabs ESCs is that Turnigy suddenly changed the design of the ESCs from ATMega to SiLabs, which are a little bit more tricky to flash.
There's now loads of tutorials on how to flash the new Plush ESCs with the SiLabs chips: http://www.rcgroups.com/forums/showthread.php?t=1686498
