Every detail is wrong, excepting only that there is dirt. When dirt is your best feature, you have to fall back on hype.
Venus and Mars are both extremely difficult environments, overwhelmingly moreso than Antarctica, the middle of the Takla Makan Desert, undersea, or in orbit, and also much harder to get to and from. No one has attempted living sustainably in any of those, and there is no proof they could if they tried.
So, only billionaires' public fantasies make them seem doable at all. Of the two, the cloud tops of Venus are somewhat less all-around hellish.
Mars is also a stepping stone to the belt and the outer solar system and like it or not it's our next frontier.
Antarctica isn't going to yield you the same reaches as the belt will or heck even Mars because currently "polluting" Mars would actually be beneficial or at the least immaterial.
Humanity needs a new frontier to expand too, we tried making space our next frontier but it didn't caught on, maybe now it will if not it will be quite sad imo as it would leave the digital frontier as the only other frontier to expand into.
Phobos could be useful.
Venus: Water vapor, air pressure, warmth, gravity, more sunshine.
Mars: Dirt.
You just get a lot of dirt, and a lot less of the others, but brine can be purified, air can be compressed to get pressure, useful minerals can be mined from the soil and rocks, which unlike Venus, isn't under a scorching acid bath.
Gravity is 1/3 normal, period. Sunshine is at 1/2 normal. Warmth is lacking. Air pressure is lethal.
When you have to lie to make it seem appealing, it is the lie that sticks, not the appeal.
But even in ideal circumstances, manufacturing Earth-normal gravity on Mars will not be possible.
On Venus, you have to deal with high temperatures, acid rain, the bigger gravity well, and the ever-present danger of your floating city falling down. On Mars there's a lot less of everything, but ruling out a meteor, the things you have to deal with are gentler. Not even a dust storm would kill you if it caught you outside in your spacesuit, as it would feel like a breeze.

Granted, it's not impossible - ocean oil rigs operate at those depths - but they're not operating at 500 degrees celcius.
Yes, Venus can be as habitable as Mars, but there's a big problem - like it or not, we have to extract resources from a place to live there, and there just isn't much we can extract from Venus. Extracting any resources from the surface means mining them from a hellscape, and then lifting them out of the gravity well into the clouds. (Though, to be fair, maybe we could just park a few asteroids in orbit and use those.)
