so, this is usually what people want. If you want more of a challenge and more (mostly) irritating gameplay but want the better items, id go for crimson If you want a more relaxing time and ripping that eater of worlds apart, go for corruption, though crimson is probably better, the nostalgia would be a big thing for corruption since its been here since the start I personally go for corruption. Its more appealing to me, and who doesnt like being able to split that eater of worlds and have the fun of ripping it to shreds? I don't.
I like crimson better. I think it's because corruption is more boring in structure, while crimson has these huge open underground areas
The chasms in the corruption to me can include some interesting shape, but most of the time, I can agree on that.
