If one believes the new sacrament of ordination and the new formula for consecrating bishops are valid, then I don't see any reason for going to an SSPX mass as opposed to the FSSP or Indult, other than driving distance.
WHAT!? So you have no problem with the indult mass' condition of publicly accepting the novus ordo? That's shocking. The whole reason we're in this mess is because of V2 and the novus ordo, and the indult mass is related to these 2 evils.
In the very beginning, the Anglican mass was the EXACT same as the True Mass, except one had to accept the condition that the pope was the head of the church. In the same way, the indult mass CAN (though not always) be EXACTLY the same as the True Mass, except for the condition that one accepts the novus ordo.
No. One cannot accept the novus ordo, even implicitly, for to do so is a compromise of the Faith.

To get back on topic, the FSSP priests (some of them) may sound "great" and "catholic" but they have compromised the Faith by accepting modernism. In the short term, there may be solid priests as part of their group but once rome gets involved, their seminaries will be infiltrated and modernized. Their priests may sound good, but so do some protestant radio broadcasts.
