Your impression of CI3 over others?

I have tried Laravel(this is not PHP for me), FuelPHP(I like this one too), Phalcon(this was fun), Yii, Symfony and countless more but CodeIgniter is the best, simple & fast, easy to extend and you can do one thing more than 10 ways
Has a good set of libraries and tons of tutorials and scripts online
And the documentation is more then good

With CodeIgniter even the sky is not the limit

Agree, CodeIgniter is the smaller, simpler and faster.
FuelPHP is very nice but they are rewriting it from scratch (it seems).
Laravel looks like holy grail but... its huge, slow... maybe for big enterprise project but not for smaller once.
