Hero is definitely big enough for you and the black leather version I have at a similar build, the same weight as you but slightly taller is also a great office chair as well in terms of functions, looks and value.
The Epic will be too small for your legs like any other chair with racing banding on the sides. That Orange looks OK but like many other 'designer' office chairs it's just mesh.
I saw 'positive' reviews for one of the very expensive designer office mesh chairs, despite the fact they mentioned it had also eroded belt hooks on two pairs of trousers. That mesh isn't a patch on a solid chair for comfort or looks whatever the price or designer IMO.
Not easy finding a high grade black leather office chair as good as and with as many functions as the Hero for the same price. I spent a long time looking. Plenty of low grade leather office chairs lacking functions with soft foam and composite 'leather' that eventually rubs away AKA many a cheap leather sofa.
