Eh, honestly only thing horizontal is good for is media, any documents/code is better in narrower vertical columns.
Honestly my perfect screen for work would probably had something like 1:1 ratio, so I can have 2 nice columns of code that are tall enough that can be split horizontally if needed while still being useful.
