Why not just use reddit as intended, subscribe to only the subreddits you're interested in? Isn't that the whole point of reddit, to aggregate all the types of content you're interested in?
1) I dislike the fact that the Reddit aggregator mixes together all the content from the different subreddits. I like having them segregated, with equal "airtime", on a single screen
2) I dislike the fact that I have to manually visit Reddit everyday, in order to "not miss out". If I didn't visit the site yesterday, then I have to make up for it today by sorting by week, instead of day, which will then show me lots of duplicate content which I've already seen. There's no easy way to just get the top content from day-X
3) This is more subtle: Suppose you visit Reddit everyday at noon, during your lunch break, sort by top:day, and then never visit it again for the rest of the day. This means that you will never see any posts which were posted in the couple hours before noon, because they haven't had sufficient time to rack up the votes. You can miss out on a significant amount of content this way
