Yet another answer may be "it doesn't matter, as long as you learn _one_". It may simply be too early to predict which one will pay dividends, but it is certainly true that a person will benefit their career and passion for software by delving into either Groovy or JRuby. Flip a coin and go for it! I am less enthused by the other options, including Jython (sad to say... I love it and Python). Yes, the best answer may well be “learn both”.

The fundamental premise of Ruby was flawed i.e. we don't want to leverage Java, Java has become too bloated. Nonsense of course, Groovy is superior by design because it was conceived correctly - the whole point is that people want to leverage Java. Groovy has everything Ruby has and more but without that fundamental flaw. Now we see JRuby basically admitting the mistake and attempting to graft Ruby onto the JVM and to work with Java. But it can never do so as well as Groovy which started from this premise. JRuby is just a poor Groovy, why bother? Groovy every day of the week and twice on Sundays.

Both languages seem good, but I'm a speed nut, and simple can't stand the slow speed of the ruby interpreter. Yes, I know there are things in the works to improve ruby speed (compiler and/or specializer), but they're not here yet Jruby is interpreted too, it's not compiled code. Groovy can be compiled and performance is pretty close to java. As far as I can gather it's like 80% or more of java's speed when running similar code on the same JVM.

If you have acces to the books (Groovy:GINA, Ruby:the pickaxe) then you'll have an easier and happ experience.

True, but the same applies for all other JVM scripting languages at present.

> The books describe outdated versions of the language.
Groovy in Action describes the latest 1.0 (non-beta) release

> Grails is indeed impressive, but I am not confident that it is built upon a solid foundation.
It really depends if you think Hibernate and Spring are a good foundation or not.

You said it yourself, Groovy grew out of Java, so the learning curve is easier. In a way, you can say you learn less by learning Groovy. Ruby, having not grew out of Java, has a different way of doing things, so you do stand to learn more. If you're looking at learning something that will give you a different perspective on programming try Ruby. If you're looking on something that might nicely compliment your skill set, Groovy might be a better option.
