prove to me why i should switch to vertical growing

Title says it all I am very interested in vertical grows but it seems like a lot of hard work for the same product and same amount of that product
Can anyone prove to me you harvested more than a gram pre watt in a vertical garden

Please don't reply if you havnt done it and you just heard about it I hav searched and searched all about very grows and it seems like most of them get about as much as a normal grow
Thanks in advance for anything helpful and I will up ur rep if it is helpful

Here's a simple illustration. This is from DIALux, an industry standard lighting program used to calculate luminance. Same wattage/lumen being put off by each fixture - compare the amount of white space. Aside from eliminating restrike the vertical offers a much much larger surface area than a flat top.

Good example Gastanker

From a mathematical perspective. A 4x4 canopy is 16sq ft.

If you have your plants 24" from the bulb in a vert system and only a single row of 3' tall plants (small) you would have a surface area of 37.68sq ft - over twice that of the 4x4.

Here's a master pulling over 2g/p with vertical
