Give it a try. The languages are actually very similar, on roughly the same level of "high-low-level-ness", they both come batteries included, both are very mature and refined.

Some things you may find nice are: the elegance and ease of use of blocks instead of explicitly declared lambdas, the standard library full of nicely named methods with aliases for the most used ones (e.g. array.map / array.collect do the same thing, some people hate this), the {do,if,case,loop}-end syntax that doesn't fuck your code up when you just quickly comment these parts out without reindenting the rest, and if you're into OOP (as in OOP, not explosion-in-the-factory-factory), then of course the hardcore OOP-ness.
