Your impression of CI3 over others?

...
The only think I think it should have a built in HMVC frame work rather than adding third party.

exactly , i am not guru ! and have used joomla for 2 year to create sites and custom modules, but codeigniter is easy to learn, easy to use and easy to extend, laravel or others have good points but for me and our team CI is very good select,  just i wish we have HMVC and some other things in next release of CI,
