I've read both versions, and while the newer one is definitely better, there's a few minor things that bothered me (luckily I found a program that can do search&replace for all txt files in a folder, so I took care of all the things)
The main thing was that they used the "western" name order (as in Rena Ryugu instead of Ryugu Rena, same with all other names), which has always bothered me in TLs in general for some reason, I think because it's immersion-breaking when japanese people do it "wrong"? Anyways, I switched all names back to the japanese name-order...
Next was the fact that they changed Keiichi's allowance from 1000yen to $10, but left all other money-values as yen (also 1000yen were more like $4.xx in 1983 iirc), so that got changed back as well
The other 2 things are more personal preference: They changed Rika's "mii" to "mew", I dunno which version would be more correct, but I perferred the "mii" in the first TL
Other one is Mion referring to herself as "this old man" at some points, while it was "Uncle Mion" in the first TL, I changed that as well
General choice of words and Satoko's speech are a lot better though, so including all the changes I made, this TL is way better than the first
