God knows that not all Litvish yeshivot [based on the Gra] are all of the same caliber. Especially the places that are shiduch yeshivot.  [That is people are there for the name of the place in order to get a good shiduch,] This becomes apparent in the approach of people that come from there to use Torah to make money. Often this is not limited to Shiduch yeshivot but places that people and out there just for the name.

But you have to ask yourself what the alternative is? No other kinds of places have authentic Torah.

And there issue is not just authentic Torah which one could learn on one's own. I mean one could learn Tosphot, R Akiva Eiger , the Ketzot etc in order to see and understand a drop of the depths of authentic Torah on one's own. But the way I see it that this is very difficult to do without an environment of Torah learning.

 And almost no one stands against the Sitra Achra [the Dark Side] that has penetrated into the Torah world except for Litvak yeshivas. Most of the religious world is highly highly compromised by the Dark Side. At least the Litvak yeshiva based on the Gra provide a kind of shield.

The two places I was at were both great: Shar Yashuv and the Mir in NY. But from what I can tell most Litvak yeshivas are great. Probably the best is Ponovitch in Bnei Brak. [Or off-shoots of Ponovitch.]

If only there would be a straight Gra type of Litvak yeshiva in my area I would rejoice.

But there is not. So all I can do is to try to learn the one single volume of Rav Shach's Avi Ezri that I do have. [It is the only Torah book that I have.]
