You cannot beat the math or the physics, an opinion means nothing!
If weight is basically static, then the smaller surface area results in a higher peak energy, the principal a bullet works on. If this wasn't true I could fire a Nerf ball through your head at the same speed as a bullet, but I can't as it will just splatter on your head leaving you pudding faced!
Improved control comes from a more uniform larger sweet spot, but it has a lower peak power. So you can hit further off the central zone but still get basically the same power, although it will be less peak power than the central zone of a smaller sweet-spot. The power distribution across the surface is represented by a bell curve, small surfaces have a sharp steep curve, large surfaces have a blunt wide curve.
The top spin effects of big racquets come from the ability to hit in the larger sweet spot, more margin for error under extreme angles of incidence, but it's nothing to do with peak power.
If you want to drive as far as Tiger, or hit as hard as Federer, do not use big racquets or cavity back clubs! But you then have to accept that hitting outside the sweet spot will have a more dramatic effect. Anyone who has used blade clubs knows this finger-breaking effect!
