I believe what you're referring to is the difference between narrow and wide band sensors. Some manufacturers use wide band sensors which display continuous readings- flat line- if you prefer. Typically those are used in conjunction with cheaper narrow band sensors resulting in one jumpy line, and one flat line on those readouts.
Those look fine dude, like Tom said. IMO your bank 1 sensor needs to be replaced since it's reading lower than the new rear sensor. It's working, but it would put out more voltage if it was new. You'll probably pick up 2 mpg with a new front sensor.
