I've actually tried the soylent powder from a friend and found it was great.
And while you can find food prep to be a satisfying experience, i can't. I've tried, many times, and it just feels like pulling teeth. From going to the market to buy ingredients, to planning out the meals and portions, to actually prepping and cooking the food. It's boring, tedious, and not something I enjoy at all.
The "better taste" can actually be an issue as well, because I tend to need to force myself to eat even when I'm not hungry, and eating something that was prepared hours ago that doesn't sound that appealing any more while not really hungry isn't a pleasant experience.
I'd rather have a shake, or eat a bar, and go on with my life.
