too often i think

i have a hard time giving an articulate answer when asked "what's so good about Dostoevsky?" i feel that i don't read much, so i should probably read other authors instead of Dostoevsky all the time just to *cough* come across as less biased.
Crime and Punishment - twice at least, plus fragments here and there. fragments i've gravitated towards:
- Sonia reading Lazarus' story aloud
- Svidrigailov with Dunia in the room, before he meets the jewish Achilles
The Idiot - 1/3 of the way through
The Brothers Karamazov - once, but read some fragments several times:
- Ivan's conversation with Alyosha in the tavern (without the Grand Inquisitor)
- Zosima's duel and the mysterious visitor
Notes From Underground - first part maybe 4 times, second part once.
i finally picked up a box of the Pevear/Volokhonsky translations, and i can see what the fuss is about.. but i'm still partial to how the Garnett translations flow since they're the first ones i read.
