I can understand the OP's frustration I think. I felt a bit like that when I first switched from DE's to straights and couldn't get the hang of it for a long time. All I would say is that with effort and perseverance comes attainment. Throwing superior tools away because you're not able to use them yet isn't the way to improve.
I would strongly argue against the 'superior tools' and 'not able to use them' part of your post.
When cartridges were introduced men ditched their old DE razors in their millions. These men knew nothing other than DE shaving. If cartridges were 'inferior' they would never have sold, and sold to men with many, many years 'practice' with DE razors.
It's hardly rocket surgery.
