Teri,
Well, it really doesn't HAVE to be adjusted in city driving but if you have it set on boost #3 (most boost) which I did because my trailer is quite heavy, then when you drive in the city that much boost is too much and makes for a jerky stop when you lightly touch the brakes to come up to light. The boost comes on strong, the trailer brakes come on strong and then almost immediately back off to the rate of deceleration. If you don't mind that initial jerk then there is no need to change the boost. Keep in mind that to change the boost you just push a button once or twice. No big deal.
I kind of think you might be trying to overthink this. The Prodigy will do the job and do it well. If you have some money to burn then perhaps the other controller would be a good choice too. I know what I did for many years and was completely satisfied. If I were going to tow a lot again (I'm not ) I think I would purchase one to try it out. Kind of did the same thing with the Hensley years ago. :R
Actually, truth be told, I would like to see you get the other controller, use it, and report your impressions on this forum. We could all use a bit of educating.:)
