Should I buy the original CD or remastered?

I'm particularly talking about CDs from the 80's and 90's. I keep hearing about how remastered CDs are a victim of the "loudness war" and basically are just compressed to hell, therefore making the overall quality worse. However, I have both the original and remastered versions of Blind Guardian's Somewhere Far Beyond (1992), and all I really notice is that the remastered version sounds louder, but not of worse quality. Actually, its increased volume helps me enjoy it more compared to the original, which is, in all honesty, hard to hear. I'm not sure if it's just that album though, and were I to get other remastered albums I'd notice a lot worse quality.
