TIFF deflate question

I did an speed test in Shake with different formats, all 4096×2304 @ 16 bit

FORMAT = read time per frame
SIZE

TIFF RLE = 1.3 – 1.4 sec
54.4 MB

TIFF 16 LZW = 1.5 – 1.7 sec
16.6 MB

TIFF 16 deflate = 0.77 – 0.88 sec
15.3 MB

DPX Bottom to Up = 0.97 – 1.01 sec
36 MB

DPX Top to Bottom = 2.7 – 2.8 sec
36 MB

EXR piz = 1.7 – 1.73 sec
23 MB

IFF = 1.04 – 1.11 sec
48 MB

What pros and cons are there with the TIFF deflate? I couldn’t open the file in Combustion but it opened fine in djv view. I read at Wikipedia that it is some kind of LZ78, huffman, zip-like compression.
