I say NO to Brazilian IC in general. Not always, of course - you know how I always say that everything has to be adapted to the situation, and I can see that in some cases you may want a Brazilian IC. But in general - no.
Why do I say generally no?
The focus of the Axis attention is usually Moscow. When Moscow is the focus, the Allies need to either reinforce Moscow or attack one of the Axis powers to the extent that there’s a real threat. A Brazil IC is too far away from the action to reinforce Moscow or add momentum to an attack on either Germany or Japan.
Sure, a Brazil IC lets you have the ability to produce invasion forces on an instant. But you have to blow 15 IPC on it to set it up, then you blow on the order of 8-14 IPC or so every time you use it, and that’s when you’re just setting up either an Atlantic or Pacific fleet. Even later in the game, when most of the shucks are set up, I think I would typically want those IPCs for air units.
There are times when a Brazil IC may become important, I would think later in the game (turn 6+ or so) when/if Japan has set up shop in India and is dropping units into Africa. But I think it’s situational; it isn’t something you shoot for from the start.
If I want to keep Africa with Allies early, I’ll either push infantry by dropping early to Algeria, moving to Libya then Anglo-Egypt then Trans-Jordan, but that often sees the Allies running into a Japanese wall at Persia. Alternatively, I can produce tanks with US on US1, land in Africa US2, and race through Africa US3+ with light infantry backup following; US4+ sees the Allied fleet in the Atlantic moving north to set up the E. Canada-UK-Europe shuck.
Of course your post was probably about the second reclamation of Africa (Germany takes, Allies reclaim, Japan takes, Allies reclaim a second time). But at that point, unless I’m facing a big bomber squadron, I’ll typically have attained my goal of reinforcing Moscow and/or threatening one of the Axis powers. NOT ALWAYS, of course, and as I mentioned, I may see a use for a Brazil IC in some specific situations, but again - it’s situational, not something I’d gun for from the beginning.
