For my part, I prefer madeira to port, though I am open to being converted should I happen upon the magical liquid that will do that. Following is a real life situation:
Last Friday at a local wine tasting I happened to bring in the 1968 D'Oliveiras Bual (thanks Roy for the suggestion!) for friends to try, the majority of whom have good palates. It was a smash hit with men and women alike. Last night I was out with friends and decided (after posting TN on the 1977 Royal Oporto, which I upgraded to a score in mid/upper 80s) to try a glass of 1985 Dow's (which incidentally had been open 10 days according to the proprietor). I have to say that it did not blow me away and in retrospect I felt perhaps that I had been unfair to the 1977 Royal Oporto which next to this Dow's was far and away better). This glass was also passed around to 2 gentlemen friends and one female friend. It was readily dismissed as not particularly interesting and everybody went back to the Merryvale 2003 Beckstoffer Vineyard X we had been quaffing. Everyone indicated they much preferred the 1968 Bual they had the week before, which they had a vivid memory of. Maybe 1985 Dow's just isn't the stuff to bowl anyone over, including those among you who are much more familiar with many many ports. Or maybe it is a great representation of what great port ought to be and these 4 individuals simply aren't "getting it". Maybe the 2 females are showing the assumed preference for madeira referred to in earlier postings, and maybe the 2 males are on the tails of the bellcurve in expected tastes of males and inclination to port.
Whichever the case, I will not stop at the 1985 Dow's but will trudge ahead and try a few others. It may be that I will never love port as much as I love madeira (incidentally, I am not a fan of "sweet" so much as a rich complex madeira), but I expect I will eventually come to have a finer appreciation of ports than I do now. After all, one does need to mix things up a bit for a change of pace. Furthermore, one's budget doesn't allow for regular vintage madeira drinking

so there is a practical aspect to finding a worthy alternative.
