I agree. I've been using Rails for 12 years and it is my second favorite framework :)

Lucky and Crystal are missing the ecosystem, which the article mentions, but it also adds a lot that Rails is missing. Lucky is much much faster and the speed is effortless. Rails can be fast, but based on my experience so far, you have to do some work to get reasonable speeds.

Lucky and Crystal have also caught a lot of bugs, which makes development much more pleasurable, and happier customers.

Right now, it probably takes longer to use Lucky and Crystal. Like you said, the ecosystem is lacking so you often have to write code that Ruby would have a gem for, but in the long term, this will be solved. I'm very confident of that.
