yeah glass wont get sunburnt and look like old car headlamps; and the curvature catches stray light from the side and lights up and screws with the images, the tiniest amount of dirt/water spots just makes em go haywire.. any time you have a dome over the lens you have to spend an absurd amount of time testing it under all possible lighting conditions to ensure its not going to blind its self.. Indoors domes are much easier to work with since all the light-sources are static and the environment is controllable.
turrets often have less lens choices and external alarm/audio inputs than bullets, and bullets have a smaller install footprint so if your putting multiples on a post or junction box its easier to accomplish with bullets.. lots of bullets still have rings of round diode IR LEDs surrounding the lens and that creates a halo effect on the image and attracts bugs to the front like nobody's business.. but you can get those with eyeball turrets too.. Surface mount LXIR lighting is so much better on both Turrets and Bullets.
Head to head, 2 of the same cameras with same lenses and IR capabilities Bullet vs Turret usually comes down to: turret looks better installed, especially in residental applications.
