Y-dna upgrade or SNP pack?

[Circassian]

I took the Y-dna12 test first, it came out as J-M67 but I want to proceed to find out my subclade and I can't decide to either get the J2 - M67 & L24 SNP Pack or to upgrade to Y-DNA67. What would be more beneficial in terms of results. What would you suggest?

Nevgen says i'm 96% J2A1 L26>Z500 and the SNP pack does include Z500 so Im good on that but then again maybe the upgrade will reveal more information?

I spoke to 2 project leaders, one is telling me to get the SNP pack the other is really pushing me to get the upgrade to unlock more matches on the FTDNA database and he says the upgrade results would be the same same or even better than that from SNP pack. He actually wants me to get the full-Y but I'm not sure.

The difference in cost is only $20 so that is not big factor for me.

If its possible do Big Y.

And otherwise do Nebula (WGS costs 300$) and it gives you y-DNA, mtDNA, autosomal + ability to upload on Yfull and FTDNA for y-dna matches. Don't bother with SNP panels, I've also done that and in the end I've done a WGS so the panels were a waste of money.
