ADA 2012 programming language or GROOVY scripting language ??? Hard choice – Torture lol

HELP !
ADA 2012 + Microsoft .NET Framework or GROOVY + Java/Spring Framework ?????????

Groovy and his convention-like frameworks Grails, Griffon  and Java/Spring ecosystem is well suited for my agile approach on future control system projects but ADA 2012 is clearely more robust and simple  and .NET framework can complete the  omissions of ADA ecosystem. Two of them  have interesting features , Hard to choose XD

Looking for GROOOVVVYYYY

For my Teamwork Framework project and Rapid Prototyping Tools project for D.I.Y. Makers ( Do It Yourself) in Robotic and Mechatronic , I am studying a very interesting programming language Groovy and his “Ruby on Rails“-like framework  called Grails . Groovy, the power and rich ressource of java combined with the easy of Ruby, Ruby on Rails, Python and smaltalk.

Groovy is an agile and dynamic language for the Java Virtual Machine. Builds upon the strengths of Java but has additional power features inspired by languages like Python, Ruby and Smalltalk. Makes modern programming features available to Java developers with almost-zero learning curve.
