A quality jigsaw is one of my favorite tools, and a seriously good DIY best buy. Armed with the right blade, you can cut all sorts of materials into nearly any two-dimensional shape you please. And most-importantly, do it safely.
But it's flexibility as a creative tool is also its liability. Like a pencil, it can go in any direction, but in the hands of a human being, those directions will never be without the marks of our innate imperfection. Straight lines can be accomplished with a fence, but a perfect circle. You can't draw one by hand, so don't expect yourself to be able to jigsaw one either.
At least, not without a little help.
Does the tool make the man, or does the man make the tool? Like most things in life, the answer is somewhere in the middle. You need to know how to properly operate and care for your tools, but the right tool/jig can make or break your project.
Of course, I'm just an active hobbyist, and my tools reflect that, BUT every single one has a time and place to be used, and we've formed a deep bond over the years. Some are used a lot more frequently than others, and so here is a list of most used tools that I have in my shop...which my wife lovingly refers to as “just the garage."
