I used some Ultrafine 400 in 120 and the Ilford Pan 400 in 35mm (which is supposed to be the same as Ultrafine 400).
Pardon the compression level on both shots, as they were uploaded to Facebook, and suffer from their compression algorithms.
Both films have worked exceedingly well for me, and I think if you can't get good results with them then something in the work flow needs to be addressed.
Out of the two images the OP uploaded, the skin tones of the girls are not very good, all grey and lifeless. Bad light? Not enough processing? Not enough exposure? A combination? The second shot looks like highlights that are too thick due to overexposure, possibly in combination with overdevelopment, of subject matter in terrible lighting.
