The problem with Kuerig for the real coffee lovers, is it makes the coffee too fast. Good coffee requires hotter water and more time with the beans soaking in it.
There are others, but they are all imitations of the Kuerig, which doesn't mean they are bad. They are all trying new features and gimmicks to attract business, some might be useful for some.
But, I just want a caffeine shot, some flavor is good, but that is what flavored creamer is for. So I'm happy with my Kuerig.
I played around with a French Press and electric tea kettle for a little while. It only take a minute or two longer than a Kuerig but makes a much better quality mug of coffee for the coffee purist. The electric kettle will boil a quart of water in two minutes, you pour it in the french press with the coffee grounds, give it a minute with a couple of stires, then press down the filter and pour out your cup of coffee. BUT, this is not automated, it requires a good 5-7 minutes of your undivided attention and then you have a french press to clean afterwards, so less convenient. The extra effort might be worth it for a true coffee conisierre.
The only other thing between the two would be the Coffee machine that makes a pot off a timer.
