You mentioned that you can't use 2.4Ghz without an OTG cable. This is not true for iOS devices. I see you use an iPhone so you should be able to switch to 2.4GHz without any trouble. In the DJI GO app, just select 2.4GHz, scroll down and then choose the channel with the least interference (smallest green bar). After that your Sprak will reboot, your video feed will turn black and after it's done rebooting you're on 2.4GHz.
Can I define perfect? Well, yes: what I meant is basically what I've written above. It's easy to switch to 2.4GHz with a device running iOS.
I know what you mean though. You were thinking about range and image transmission quality. Well, I mainly fly in rural open areas with little to no interference at all, which means that the 2.4GHz band will perform very well and I can easily reach and surpass the given maximum range in CE of 500m (I have seen video footage of people reaching +1500m with their spark in Europe under ideal conditions).
But, flying in close vicinity to buildings with many different WiFi networks, bluetooth connections, etc. will definitely cause some trouble when using 2.4GHz as this is the band most WiFi routers use. So the available channels will get very busy (indicated by red bars in the DJI GO app) and thus lead to a poorer performance of the drone.
Using the 5.8GHz band in those situations should improve the performance a little, but bear in mind that when flying with 5.8GHz the maximum range for CE is 300m under ideal conditions. So don't expect too much. (I have used 5.8GHz on multiple occasions with mixed results. I'm only using it when I fly in the city and within 50m or so.)
Hope that helps,
