It reminds me of this.
I never used the middle handle myself. It just felt very cramped and unnatural, and you couldn't reach the L button.
I liked how it was designed to do both both digital and analog controls well, which is also why Sony are still the kings of controllers.
I have always liked the way the normal N64 controller looked.
One of the only things that bugged me about it is that the control stick hurt my thumb after long play periods.
The control sticks themselves wound up wearing out over time and that also bugged me.
