Any change in direction builds friction. The smoother the change the less friction but the more friction built up the more likely something will fail. Pump over heats/fails prematurely, tube comes off the barb fitting.... Not friction related but the more bends and twists means more opportunities for a kink.
There's potential risks and drawbacks to any setup. There's no perfect solution that satisfies all scenarios.
