In my experience, I also find that public davening – other than Shemonah Esrei – where there is a “loud din” caused by everyone reciting the pesukim or brachos out loud are the most uplifting. I feel the engagement, the purpose, and the noise is angelic (literally).
I think, however, that The Frumguy and WolfishMusings (from 3 months ago) aren’t talking about that type of situation. They are talking about an individual who is shouting over the din – and may not even be in sync with the tzibbur.
So while I agree that davening out loud is best, one must remember that davening with a minyan is about the tzibbur, not just oneself, and adjust accordingly. There are plenty of opportunities to scream praises of Hashem at the top of your lungs throughout the day. When I walk into shul, I prefer to be a part of the din, not over it.
