which is the easiest and most recommended way
The easiest way is to sow some seeds in the forest and do nothing else until harvest. You can achieve great results this way. You just need to take an attitude of not really caring what happens. Your'e not doing any work except planting and harvesting, and you'll get weed for the effort, sometimes massive amounts. Most people agree that DWC (deep water culture) is a great hydro set up for begginers. This is very easy also, and done properly will yield much more than soil. For effort vs yield this method can't be beat. Your title mentioned aeroponics. It is a massive yielder, but not easy by any means.

bud grown in soil tastes better and has a way better high to it
This of course is utter nonsense. For various reasons hydro can yield some of most potent weed possible. I'm not saying you can't get potent weed in dirt, but hydro is by far the better option for a great many reasons. Do words like bigger, better, faster, healthier and more, appeal to you? If so, your the type of person that should choose hydro for your grow method. As far as dirt weed tasting better, this is a load of crap. You can make your hydro weed tast like anything you want, and it's way easier to do so than if the weed was in dirt. How about vanilla, or mint, or coffee? If you are worried about chemicals or a chemical taste, you can grow all organic. Whatever you do, to both hydro and dirt weed, it will affect the taste. However, it's much easier to completely rid your weed of all unwanted taste if you are growing in hydro. You simply use water instead of nutrients the last week or so. Try getting the fertilizer taste out of dirt weed that easily. Many people don't flush like this, so sometimes people get some hydro weed that they didn't like the taste of. I usually don't flush, and my weed tastes just fine.
