Lol, macros74, yes i have E-D files (and some simple background description (have a lot time and nothing to do

)), but about comparison

It's hard in some way,
polished-used-raws are R2, but made really shitty, they have many jpeg artefacts, but more detailed, E-D have less artefacts, but worse detailed in some scenes (for me E-D's just more watch-able, since i still waiting Yabai (lol i think it's forever)).
Also E-D'version have R1 official subs, i have no idea what here can be compared
And replace? I think it's nothing to replace here

chihiro-polished = fansub, E-D = R1'rip, but i don't know since Clannad by coalgirs was rejected.
