i prefer DF-UDT because of the likeness and sharpness of the result over Liae in any kind of setting at all.
Dims are not so high about 320/102/102 imo - but i always reuse the models for single src - so in this case the Model is about 2 mill iters and trained using the src anne hatahway faceset before over 1 mill iters on different projects.
i donĀ“t switch src faces ever on models, prefer to copy my master model an make a new one and let it stay there.
