So, then you would want to see Sonic change and be more like how Sally has been wanting him to be, but just not as pedantic as her?
Yes and no, I don't want Sonic to learn to completely change who he is, but I still want him to grow and accept sometimes his way isn't always the best, but Sally should do the same with her's to an equal level. Basically both characters learning from the other that there's a time and place for either strategy, or for a compromise of both, rather than one being more consistently stable than the other.
Again this seems to be assuming the idea that any spontaneous approach is reckless and suicidal, and the moment he goes about things in a clever manner he is suddenly meticulous like Sally, which I think is oversimplifying it. He can go by his heart but still be clever about it. As said in other medias he is shown to be rather collected and resourceful, aspects that help him go through the motions when other more tactical characters may panic. It would actually make more sense if he shown these aspects more since it give more justification as to why he overestimates how often it would work.
I think Sonic comes off as reckless because he represents spontaneousness to a much greater extreme than Sally does, taking STUPID risks he should know could be hard to evade if they fail, not to mention conveying all the traditional flaws of a character holding the Idiot Ball, being arrogant, childish and refusing to listen to anyone until it's too late. Sally was meticulous, but rarely in a situation that it could be a hinderance, and in most cases it had the potential to be she was far more rational and flexible than Sonic and so avoided the same moments of stupidity. Be it merely the circumstance or her greater lucidity she was never meticulous to a flawed extreme, so we never really saw the downsides of her methods.
One could argue if Sally had even a couple similar screw ups as Sonic earlier on and thus grown into this disposition, this would have came off as effective character development, and make their unity in the final points of the show all the more meaningful.
As it is however Sonic was the only one who needed to learn to prioritize his ways, to the point that in Archie's future he will just depose of his 'like the wind' ethics and become Sonic's king and follow standards exactly as Sally wanted things. Supposedly Sally never had to make the same sacrifices and compromises in life because the story skews her way to look more stable than his. As such it is not equal development, it's too much for Sonic and too little for Sally.
