i think i'm going to have to disagree with you there cam, there is a difference between the daiwas despite them all sporting similar features, the difference being build quality(longevity).
with the cy and exceler (both similar reels) there's no doubt that you get a lot of bang for your buck, but i think that after a year or so of using them, they will be relatively worn whereas the Tierra/Advantage/Sol will still be performing as new. the more expensive reels can take more punishment and for longer whereas you may find the drag failing etc in the cheaper variants.
just my two cents
back to the topic at hand...daiwa offers more for your money in the mid range reels i believe. so Tierra gets the vote for me, although there is a bit of a price difference between the two, so a better comparison for the price would probably be the Daiwa Advantage/Sol vs Stradic
