To paraphrase Ansel Adams (who was speaking of cameras), "There is no one best tool for the job, only the best tool for the kind of thing you're trying to make."

Another way of saying it is that the world of software is so vast, from DIY homegrown to open source libraries to closed commercial apps that there isn't one "best" of any of it, or even 10 best.

I'd say your explorations will take you the furthest if you focus on a problem domain, learn all about it that you can, then find out what software exists in that problem space and whether or not the world would benefit from something new from you in that area.
