Halo or Aeroscreen?

Motor Racing - Formula One World Championship - Russian Grand Prix - Preparation Day - Sochi, Russia

Red Bull will test its cockpit protection concept - dubbed the Aeroscreen - during FP1 for the Russian Grand Prix. Daniel Ricciardo will run the device during his installation laps in the same way Ferrari tested the Halo during pre-season testing. While we can only make observations based on aesthetics at this point, do you prefer the Halo or the Aeroscreen?
