Moodle is a community. It is not just a program that you buy then use until it is replaced with the next version. Once into Moodle, you are also in the Community. You may never take advantage of that, but you are a part of it. That Community is a far more important and valuable source of support than a static, online knowledge base, or poorly maintained wiki that does not answer your specific question.
Moodle is constantly changing. Most of the time those changes are easily seen as positive, but sometimes it takes a while for people to see the benefits of that change. New ideas and things are tried, old things are sometimes dropped, but Moodle is in a constant state of renewal. Anyone can contribute an idea, a modification of some sort, an improvement of an existing tool, and anyone else can use it, if they chose to. You might want to use a new tool or you don't like a particular tool, you can change it. Moodle is there to suit your need, it is highly configurable to what you want. If you want to add something, some functionality, that does not currently exist, and not sure how to do that, ask the Developers, they will help. If that functionality does what you want, you may chose to give it away, sell it, or keep it for yourself.
You may not like the look of the out of the box Moodle, so you can change it to suit what you think is better. There are themes and user guides that will help you do that. You try Moodle for a couple of years, but you don't like it. You like what it can do, but you think it should be better. So you make it better, more suitable for your own purposes. You do not get frustrated because Moodle is Open Source, that is, it is Free Software. You can even on-sell what you create, as long as you meet the Free Software Foundation's licensing conditions.
You don't have to wait months, or years sometimes, for a bug fix, you might be able to fix it yourself, or someone may suggest a way to be able to fix it yourself.
For users, like any LMS, it takes a while to build the materials you want to deliver, but you can speed that process up - and there are some key benefits there as well. Working in teams to build whole courses rather than as individuals working on a single course, improves the collegiality of the course builders, improves individual knowledge of course materials, improves understandings of aims and objectives of each course. It also helps improve the skill base of the teams rather quickly when they are supporting one another, rather than working individually.
I could go on and on, but there are a whole range of essential benefits that you will not get with a purchased, copyrighted, restrictive LMS.
Some other products look a lot better than Moodle, but for two things. One, none of those products can match Moodle's extensibility, its flexibility nor the range of opportunities that Moodle offers. Secondly, none of them make use of the most important aspect of Moodle. Moodle is built on a range of essential web technologies. These technologies will not, I suggest go out of flavour, they will adapt to the changing word, and in many cases they will be driving that change. In this sense, Moodle will never be that far off the leading edge of that change, it will always be current, its very nature forces it to be that way. No other product I know about, or have used, does that.
