Revisiting CI

Hello,

I used Codeigniter many years ago and have since used yii, cakephp and laravel 5.
I recently became interested in HMVC and after frustrating problems with laravel 5,
I am relearning CI.

Would you suggest I start with CI3, since this is the future?

also is HMVC worth doing or should I stick with the stand MVC?

I was also eying FuelPHP, but I like the simpler approach that CI uses.

Regards,

Frank
