If you are interested in a Li-Ion battery setup please go for a saber equipped with Premium Sound.
However, the main drawback is definitely the shipping time since it can take months.
It all depends on you and no 2 sabers are ever the same.
The Obsidian Lite operates with the Standard Setup.
It comes with the same details as the clear version but with an additional feature of the internal diffusion wrap for better illumination and color mixing.
