Still on 4.4.2

Hi guys, new user of the ATV2. Im curious of the different updates of the ATV2 firmware. I bought mine used recently so i have not really venture into it much. Its a tethered jailbreak. Just want to know if im missing anything if i just stick to 4.4.2 or should i just upgrade when theres a jailbreak for the latest firmware.

Cheers !!
