I really can't see it that way, because the Church of the Vatican changed (modernized/progressed), abandoning centuries of tradition, whereas the SSPX and others stayed the same. From my vantage point it appears Francis' church is the protestant sect.
But personally I stick with the FSSP and diocese extraordinary forms, insulated from modern heresy as they are. Hope it stays that way.
The problem with the SSPX is that in order to deal with what they asserted was infidelity, they topped it with more infidelity. And that's where they fell down.
Thankfully, we have the FSSP. They have a church locally (with the full approval of our late archbishop, who dedicated it personally with the full and complete Latin rite) and they are straight-up orthodox shepherds.
