Bent Hardline: 90s or 45s?

[VanGoghComplex]

Because I've been watching entirely too much JayzTwoCents, and because Barrow watercooling parts are inexpensive and well-made, I'm doing a hardline upgrade. I bought a section of 16-12 and a couple push-in fittings to practice with, but decided that it's too hard to work with and am going with 12-8 and compression instead. There are a few short bendy runs in my loop that I think the smaller diameter pipe will be better suited to.

This is an aesthetics question. Do you guys like nice 90s and straight pipes throughout your hardline builds? Or do you like 45s and some angular flair instead? Got any pics that showcase your preference?
