I've always found bigger cars far easier to drive!
I have a Smart car (automatic) for popping out and about locally, but also drive my husband's extra long wheelbase, seven seater Range Rover (manual).
I find the Range Rover just as easy to drive, in fact maybe even easier, perhaps due to the increased height and clearer view. However, it has a fancy-pants heads up display which I'm not totally keen on, so I very rarely use that particular gadget!
Maybe it's because I learned to drive in my Dad's car, a Vauxhall VX2300GLS, which was a lot like driving a powerful sofa. My first experience of driving was a large car, so I've always found them easy to handle!
Oh, and I'm confident behind the wheel of the motorhome we share with our DS and family too! It's a manual, DS doesn't like automatics, weird!
