I just finished Toradora and The World God Only Knows and a few others, but those two really stood out to me.
Can anyone recommend some good anime or manga in the same vein as those two? I'm not sure if it's the "harem" aspect but it might well be, or maybe it's just the sappy romance / feels that I like.

Golden Time its from the same author as toradora if i am not mistaken so that.
Bokura wa Minna Kawaisou is pretty good, pick the manga around chapter 25 after you finish the anime if you like it.
For manga, i would go for Bonnouji, it has no drama and no harem but if you like romance you will probably like it.
Nozoki Ana (the manga, avoid the ova) it's borderline porn
Clannad + AS if you haven't watched it
Seitokai no ichizon
Shuffle!
Yamada-kun to 7-nin no Majo
Ore no Kanojo to Osananajimi ga Shuraba Sugiru.
Those last five are Harem with winners.
It's kind of vague for me what you want but check those.
