Personally, I have been using a wormbin for the past (almost) 4 years. You need to keep an eye on the worms once in a while, but usually it is a good option: you waste no energy, your organics decompose fine, and you can easily use it to enrich your soil.
On the other hand, you cannot compost anything in a wormbin (no meat or animal residues; very restricted amounts of citrus fruits, etc.), but the food cycler accepts all sorts of organics and the decomposition is way faster: about 1 or 2 days; depending on what you put in the wormbin, it can take a few days or a few months.
I do not have a food cycler, but have been researching as well to get it, and I guess it can be a good option if you don't want to sort your organics into "what goes into the wormbin" and "what does not".
Some people have their compost pile in the back yard without worms, where they put all sorts of organics too. Since I live in an apartment, I don't have enough space to test this method, but I hear it can be hardcore -- some people even use their urine to sort of catalyse the decomposition process.
There is also the anaerobic decomposition, in which you put your organics into a plastic bag, close it, and let it sit for months. This option is the one which produces the biggest amount of methane, because it stays airtight. Also, the final smell can be pretty bad.
All in all, there are several composting options, but my top pics would be the wormbin and/or the food cycler - even if it uses more energy (which I do not have the necessary knowledge to tell you if it's a lot or not, to be honest).
UPDATE: Soon another option will be available, the Zera Food Recycler.
