Is Venus a better place to colonize than Mars?

Venus, LetrCOs take a look:
The second planet in our solar system, it has no moons and it is the
brightest object we can see from earth apart from the Sun and the Moon.
It is pretty close to the sun compared to earth and it lies outside of
the habitable zone.
The surface of Venus is hot, really hot 467 -#C (863 -#F) and the
atmospheric pressure is immense down there (90 times stronger than on
Earth). This means that if you donrCOt melt from the immense heat you
would get crushed by the atmosphere. It is so hard to survive on the
surface of Venus that the longest a probe has functioned on the surface
is 2 hours. It probably seems quite obvious now why colonising the
surface of Venus isnrCOt a good idea.
However, a good idea may be to colonise the top atmosphere of Venus.
Up there living conditions are way nicer and an outpost or floating
colony doesnrCOt seem too far fetched because NASA already looked into it
and published a paper about in (Link in sources). The main advantage the
upper part of Venus presents is that the magnetic field shields you from radiation and, because itrCOs atmosphere is so dense, rCyEarth airrCO stays afloat. That means that if you build a spaceship and fill it with air
from EarthrCOs atmosphere it would float there (Given that the ship isnrCOt too heavy). This means that living there might be quite enyojable, given
the technology.

what planet would you go to?

Surprisingly, but Venus !!
HererCOs why
It has similar gravity to earth
In upper atmosphere you have habitable temperatures and pressure.
Only need to carry oxygen tank, no need for any other suit.
If you are able to build a structure which floats there, than even
plants can grow there
Why not Mars
Its surface air pressure is much lesser than earth, need a suit constantly
Need to carry oxygen tank
Gravity is much less, longer stays can make your bones weak
Temperatures are also extreme, your suit needs temperature controller,
and any damage to it means death

Does Venus fall in the habitable zone? If Venus' greenhouse effect could
be reversed by some means, can it become habitable based on its current distance from the Sun?

Venus is just outside (too close to the Sun) of the habitable zone,
which is an approximation anyway. Two means for rCLfixingrCY Venus have been proposed. You can build an enormous sunshade in space at the Venus-Sun
L1 position, or you can put massive amounts of dust in its upper
atmosphere. These changes will not make it habitable in the usual sense,
but they will make it more explorable. Temperatures at the surface will decline far below the current temperatures that can melt lead so that electronics are not fried there. The sulfuric acid that currently falls
from the skies only to vaporize on the hot-griddle of a surface will
remain there so that the sulfuric-acid clouds will vanish (and become sulfuric-acid lakes). Unfortunately, removing the H2SO4 from the
atmosphere will not make a large d

Why don't we go to Venus? Isn't it more livable as gravity is similar
and we can make floating living spaces in its thick air, compared to
Mars where gravity is too weak? VenusrCOs upper atmosphere does have some selling points compared to Mars. There are altitudes where the
temperature and pressure are nice. Breathable terrestrial air is a
lifting gas in VenusrCOs atmosphere, hence the design of the Soviet aerial cities below. Those semi-habitable altitudes also have enough atmosphere overhead to be better shielded from radiation than Mars. And the gravity
is close enough to EarthrCOs that itrCOs likely to be healthy, while werCOre not certain about MarsrCO 0.38G. However, Mars has some selling points,
too. For one thing, itrCOs quite easy to operate on MarsrCO surface and thus have access to the abundant
