Best practice - javascript API components VS Java API components

[gustavo_dorigue]

Hi i've come across some discussions about best practice recently and one of the points raised was around usage of java API to build components insted of javascript API. The arguments were:
1 - Javascript will be converted to java classes anyway
2 - Use Java to keep consistency across platform (other components are java based)

Said that, what technology the group suggest (best practice aka recommended) to develop components? If java based components are best practice, what is the aim of javascript technology to develop components then? 

Please note the aim of this question is not to fire a discussion about javascript vs java.

Difference between Sightly vs JSP 

Sightly Offers below advantages over JSP for better development in AEM : 
Protection against cross-side scripting injection. 
Easily development of AEM Projects by front-end developers. 
Flexible and powerful templating and logic binding features. 
Strong connection to Sling use case. Slightly only Supports HTML5. 
Using sightly components development becomes a part of Web Developer instead of a java developer.
