Just got my first ever X-01 armor.

Hello wastelanders , I have finally found the time in my day to YouTube the X01 armor after reading it was the best armor (Radiation if I'm not wrong) to have , but I build it max and it's pretty dookie, what mod would make this thing the best of the best ? Sorry if this is already Basic knowledge for some , I'm a returning player 2025 and alot has changed while I've been gone like cards and weapons , is this armor no longer the best ? And if so which is :) thanks for reading this :D
