Lean steer or standard rigid body steer for handling?

Hi guys,

First post, I am a CAD designer and about to design and build my first EV, I want to make a tandem reverse trike and type approve it for UK roads, quite an ambitious first project...

I will spend the next month or so researching to try and create a decent reliable and fun vehicle,

I was wondering, for handling, is a lean steer or car type steering better for handling?

Any advice welcome!
