I would recommend the Ultragauge in your situation. More gauges on screen at a time, better looking/easier to see display (to me, at least). Not to mention cheaper. This is where I had mine mounted in my Civic I used to have. It looks difficult to see, but I think the bottom right gauge was the only one I would have to move my head to see clearly (probably depends on your height and seating position).
I have a UG and SGII in my Escape Hybrid and I use Torque on my old phone in my Prius. The UG would hands down be my pick for a conventional vehicle. The SG only really beats it when you can use xgauges (which is does great in my Escape). Torque is a powerhouse, but as you said, is annoying to have to set up every time you get in the car.
