Probably neither would be the best choice.
The "Quantum" antenna is a marketing gimmick, basically it looks cool so you'll buy it.
The Winegard is a good indoor antenna, but is not appropriate to your location due to its internal amplifier and your proximity to some of your broadcast facilities.
FWIW, the concept of the omnidirectional antenna sounds great to customers, but to the technical person, it is known to be highly susceptible to multi-path, the bane of digital reception. I've heard it said numerous times that "an omni antenna receives equally poorly in all directions".
Because the direction to the US towers forms an almost 90 degree angle to your local towers, it is probably unrealistic to expect a small indoor antenna to be able to reliably pick up both sources without adjustment. Moving an indoor antenna around is a common fact of life.
