The neo-SSPX is as relevant today as the FSSP in its fight for the Catholic Faith whole and inviolate, despite some good individual priests.
Don't kid yourself. The SSPX is not equal to the FSSP right now.
Perhaps there is no fundamental difference in the direction they are heading -- but just the fact that the FSSP has had this position since 1988 and the SSPX has only had this position since 2012 is already quite a large difference.
That's like saying a man who has killed one or two men is the same as Charles Manson, a mass-murderer who's already been judged (and is likely in Hell).
No, the former is still struggling. He might end up in the same place as the latter. Eventually. But for the former, there is still a fight going on within. There is still much goodness that must be decisively driven out.
For starters, in the case of the SSPX there could still be quite a few priests clinging to "the old ways" even though they're not willing to leave the organization. This whole Pro-Rome thing is very recent to the organization. The FSSP is publicly known to be in union with Rome and was founded for that purpose from the beginning. Whatever "deal without a deal" the SSPX has, it's certainly not well-known. There's yet another point of difference.
The SSPX is many times larger than the FSSP, due to the former's uncompromising Trad "laurels", heritage, reputation, whatever you want to call it.
So they're not the same right now
Eventually, the SSPX will distill into something stable
. Either all the pro-Rome liberals will be kicked out and it will return to its former glory (fat chance), or the remaining Trad vestiges (including any truly Trad priests) will depart, and it will become direct competition for the FSSP and be indistinguishable from the FSSP in its priests, apostolate, parishioners, etc.
I believe the latter is more likely. However, it's going to take some time to get to that point.
We're certainly not there yet, even if things are bad in your neck of the woods, you've stopped attending/totally given up on SSPX, etc.Your subjective, local reality does not form the world-wide, objective reality.
I'm sorry to burst your bubble.
