Without knowing how many units you have, I would say a little of both. The GGC are RNG for sure, but you can get 10k 6* shards for 300 units. On cyber weekend, you had to spend 5000 units to get a 6* Nexus.
I would do around 5 GGC and save the rest of your units.
It wont take you 7 or even 11 months to save 15k(ish) units, better used towards exploring end game content or finishing abyss for now if you have plenty of units

I have about 4k units right now but since I don't do arena, my units income are only from eq and stuff.
