Symphony on Saturn is a technical mess, and the added content isn't up to the standards of the original game, to say the least. The English-language PS1 release will always be the best one, for functioning as intended and having a genuinely good script, albeit delivered through questionable voice acting. It's all in good fun.
I don't like the DXC port at all for the flavourless writing, humourless by-the-books acting that puts me to sleep, bizarre altered SFX in places that bothers me to no end when it probably shouldn't, and the ugly smoothening filter and distorted aspect ratio slapped on top of the best pixel art in the industry. I am the Wind is what it is, but the new composition Yamane did for the credits isn't exactly an improvement either.
