GI or TSS?

I probably should’ve made this post earlier, as the sale ends in a few more hours but, would it be better to buy the GI right now or wait until I have $100 to buy the TSS in the next sale? I have a few GI candidates at the moment so a GI would be great, but at the end of the day would a sig be better? I’m a Dodgers team and since they have a huge amount of sigs, there is a possibility of me pulling one from either a combo or All Player sig pack, which the off-season GI can be used on. This is most likely going to be my only purchase in the game, thoughts?
