Hello
Sometimes, conversion is weird...
I used cls-ue4d v.25.07.03.rev.1 on Sifu (last version)

I know it works pretty well because I uncrypted .pak and remove some data in stream.
With an hex editor i can see that the files is fully uncrypted.
(I can compare extracted files with quickbms, exactly the same in the uncrypted file)

With ued4t 99% uncrypted, with unreal xtool plugin around 98%
If I work on file to compare extracted files there is some diff
This makes tools like xtool missing some stream

By the way the think I do not understand, is with partial uncrypt like with unreal plugin, the final compress ratio is better

like for my tests :
cls-ue4d+srep+lolz => 12gb
xtool:mue4+srep+lolz => 10gb
ue4dt+srep+lolz= 9.96gb
