What writing program do you use?

I hated word, and man is it not worth the money, so now I just use open office. But it tends to crash and for some reason, doesn't upload to the cloud (OneDrive). Also, I might be a n00b (-and lazy), but can't seem to figure out how to formatize my documents to industry standards - a lot of lit.agents out there seem to prefer word. Should I get it again? Or is there something better, less pricey that's easier to handle and that uploads to my cloud?
