Over here we had a massive exodus from the indult to the SSPX, because of the "Bishop's" stupidity and lack of "pastoral" character with respect to those who are stubbornly attached "to the old rite."
Since it has been a literally massive polar shift from complete Novus Ordo to indult to SSPX type, what I have observed is that generally they understand a whole lot better now what the problems with the indult are not because anyone academically demonstrated it to them, but now because of personal experience. This is even taking for granted the assumption that the indult is a completely valid mass etc... Who in their right mind will take all the advice for their eternal destiny from someone who AT best is half-hearted about tradition or barely understands it. You can have all the good will in the world, but without a good formation of the mind you will continue to fall into pits and traps of modernistic tendencies or stupid private revelations which are totally fake like Father Goby, Medjugorje (or however you spell it), Bayside, "exorcist" priestly revelations, Akita, Garabandal or the latest "prophet seer" which has the latest news from above on what is going to happen etc... With an overemphasis on some physical chastisement, instead of the spiritual chastisement that is actually going on... The best Novus Ordo type will say that the only solution to the problem is prayer, and I can't disagree with that solution because it is a part of the solution. However I will add a modifier with that, Catholic prayer and not just "prayer in general." It is only Catholics that can give pleasing worship to God. However, as much as possible to learn the faith well is going to actually aid the spiritual life and prayer.
You have to ask permission to be a Catholic, which does not make sense... You end up with so many absurdities and contradictions, tiny compared to those you would in any independent chapel or those who resist the Vatican II changes and novelties. The only real thing to look out with SSPX/Sedevacantist priest is whether or not they are predators in hiding and everyone should always be aware of certain signs to look for.
Also you have to accept that the only way of being a "Catholic" is in fringe groups who are part of the new Pentecostal movement like Focolare, Neo Catechumenical way, Opus Dei, et al... This is even admitted by Ratzinger in an interview, the Anglican style of Church is not good enough for most people of unity "in diversity." This concept is so absurd... To call the Eastern Rite "diverse" is ignorant because they all stem from apostolic origin. There is no diversity if it comes from the same Spirit and same Lord, it is not multiple Holy Ghost's but one Holy Ghost. In the Conciliar Church they celebrate the more fringe groups which can hardly be called Catholic because they are so novel to tradition, they are just totally foreign...
Here is what you will see the difference from the indult to SSPX/SV'ist mass centres. A more likelier chance of actually getting valid sacraments in the first place without a doubt. Secondly, preaching that you know is actually Catholic... Not ambiguous... You can generally recommend any friend of yours to go for advice to them and know that if they follow it that it will be healthy advice.
Somewhat recently I had asked the SSPX priest about my doubts on the new Rite of ordination (how certain I was about it) and how I had confessed to x priest for a period of 2 and a half years off and on. What did he advice for me to do? He said that I can continue to receive communion for now since the Church would supply in that case for those invalid confessions so long as there was contrition on my part when confessing those sins etc... After that he said that I should go to a retreat to make a general confession (helps with the preparation), or I could make a general confession to him if I would like also, so that I can rest assured my scruples as soon as possible. I have to say that was pretty good advice, it was well balanced and he cited to me sources for what he said... He did not "punish" me for having doubts about the new rite, but took the middle road etc... He gave me sound advice that was to go resolve my doubts ASAP (i.e. get a general confession) and for now he gave me permission to go to communion. After I had spoken to him about that, I was very much at peace with the solution. This is in general the sort of thing you can expect, this would be extraordinary in the indult (in the case where you actually have undoubtedly valid priest of course).
In general those in the indult at best are half-hearted about tradition because they will by default have to advice folks to go to the new Mass if there is nothing else available (there is only one SSPX priest that I have ever heard not directly but indirectly who has adviced a friend of mine that he can go to the new mass if he so "desired" under a certain set of circuмstances). You will tend towards modernism by default, because you cannot live in contradiction for so many years without going nuts. Look at the SSPX crisis right now, and they are not even with the Conciliar Church! How much worse will this be to those that are actually a part of the Conciliar sect.
