Maybe it's just all about model size.
I think the models I've been using is indeed a bit too small.

Homogeneous vs. Heterogeneous
Homogeneous graphs also learns, around 15% final acc less than the heterogeneous ones. But in terms of the size it's way smaller, 0.074MB of parameter size while the hetero ones should be > 0.2MB
(both with SAGE layers, and level 0 basic features)

Graph comparison
Run set 1:
Grey: Old GAT
Purple: GAT with the augmentation (mean pool the attentions at each layer, mean aggregate edges) - but idk why they have more parameters!
Green: GraphSAGE
Run et 2: composer task, as the data is better we have better comparison
SAGE learns faster and have less overfitting.
Conclusion: maybe GAT is not making things better.
