Was it 4:2:0 (or maybe 4:4:4). Most likely it was GPU decoded, so you felt it very responsive as frames are in GPU already.
No way h264 will be faster on CPU than Cineform or ProRes.
Remember that with Cineform you can drop resolution to 1/2 or 1/4 and then it needs to decode just HD or half HD in case of UHD (not only that- it even reads proportionally less data from the disk).
