Lightbulb Cyanogen MOD on Note 2 is a must-have apparently??

Heya guys,
I have rooted my Samsung Note 2 and it is running Stock v4.3, mainly because I wanted to use GREENIFY and Titanium Backup. When I saw one of my friends this weekend, he was amazed that I was still running the StockRom on a rooted phone, and couldn't understand why I haven't installed a CustomROM on it, then persisted to say that the best one to have on my phone would be CYANOGEN Mod, which has tons of features and once I done so, would never want to use the StockRom again?

Now obviously I'm clueless to all the ROM business, so was wondering if someone could fill me in on whether he is talking sense and that I should install a C-Rom, or just stick with Stock v4.3.

Many thanks,
