It's difficult to compare Siege of Dragonspear to BG1, since the later was absolutely groundbreaking at the time. I think if BG1 where released today SoD would be considered superior, but it doesn't approach BG2 in terms of scale and ambition.
SoD does suffer from a design issue over the inability to backtrack, which is the fault of the plot, which attaches you to an army and makes you go where they go.

The flaw for SoD to me was that the voice acting was so subpar to what we came to expect with the rest of the infinity engine games. The artwork was also not quite up to par. The dialogue itself wasn't really all well written. The story itself was okay, but the presentation, to me, was just so...so compared to what had come before. In comparison to other Infinity Engine games it wasn't all that great. Compared to many other RPGs that have come out, it probably is superior to many.
