It really all comes down to user preferences, what their main area of pursuit is, what type of conditions they hunt in, etc., etc. There is only so much "universal application" that can be packaged into any single machine, just the nature of the beast and the technology. Make user preference performance improvements at one end and you only reduce the user performance preferences at the other. There's just no way around this. Recovery speeds are a prime example, make them faster and it comes at a cost of depth, sensitivity at depth, target information, and the number of returns the user receives. Everything is a give and take situation, every adjustment simply increasing or decreasing the amount of information one hears in their headphones. So when manufacturers install built in default/presets they are actually making user decisions for the user, which comes at a cost to those users who don't want those same preferences. Another example, some machines are more heavily weighted for target conductivity, others more heavily weighted to size and shape, etc. So while the Nox, CTX, and others are nice machines there is only just so much that can be packed into any single machine before the cost at the end of the user spectrum starts to show itself.
