I recommend 'Cupcakes, 'Rainbow Factory and 'Trixie's Funhouse, unless you're under the age of eighteen. The content in the three are all explicit; and I advise you read at your own risk.
And 'Cheerilee's Garden. That is one of my favorites.
But, as for 'Sweet Apple Massacre, well, I didn't care for that one too much, so I don't really recommend it unless your the type who would want to read something so sick and twisted. Honestly, I think it's even more screwed than 'Trixie's Funhouse. Really. It was that bizarre.
As for fan-fictions in the 'Sad, 'Romantic and 'Comedy genre, I recommend 'My Little Dashie for people who like cute stuff, but also like Rainbow Dash; and also another sad one is 'Spike Is Sad and Kills Himself. Very sad. He does this, because of his love and desire for Rarity.
In the 'Romantic genre, I don't have anything except for 'Pillow Thoughts. It's on 'dA; and I recommend it for the AppleDash/Rainbowjack shippers.
Last, is 'Comedy genre; and I definitely, with no regret of recommending this one, is 'Shining Armor Is Too Handsome. It was cute, but not too funny, but still pretty funny. I, personally, liked it. Wouldn't say I loved it, though.
That's all I have. Hope you take the time to read some of those, or atleast one of them.
