I'd go with The Arrival followed by Self-titled. Those two have a more "complete" feel and have more in common with the two albums you have. The Fourth Dimension has a couple of my favorite Hypocrisy songs, but many of the others are rather plain, and the album production is not too good. As it is older, it does not have the same types of songs you hear from the band in more recent years. (Abducted and onward) I think it's getting lots of recommendations b/c it's a *classic* and a must-own for serious Hypocrisy fans. The reason Hypocrisy fans differ greatly on the bands material is b/c there are many different "types" of songs, as you may have already figured out from the two albums you have. If you like what you've heard so far from the two you own, check out albums made after the abducted album, and if you decide you're a serious fan, get the older albums.
