I have a problem in which the models I draw keep hiding other models, not in a 3d way but in a sprite kind of way.
Its weird and annoying, is there a way to fix it?
models hiding other models
A description of the problem or an image would help.
Guessing blindly, I would suggest enabling alpha testing and/or depth testing.

Ye, it is probably a depth buffer problem. If you do not enable the depth buffer, things will get drawn in the order which they were added to Components, and NOT on their order in 3d space.
Set
GraphicsDevice.DepthStencilState = DepthStencilState.Default; at the start of your draw method.

GraphicsDevice.DepthStencilState = DepthStencilState.Default; at the start of your draw method.
If it's a depth issue, you may want to look into:
- Painter's Algorithm: Sort from back to front, draw in that order.
- Depth Buffering: Discard pixels that would be behind what's already drawn.
If you want to know how to implement occlusion culling:
- Occlusion Queries (Z-Buffer hierarchy is a good optimization)
- Precomputed PVS and portals
