Which Planet Is Easier To Terraform Mars Or Venus?

Mars and Venus are Earth’s two twins, or not?
Venus is a hot where sulfuric acid rains and temperatures melt lead; in contrast, Mars is a cold desert where temperatures can drop to -200°F (-129°C)).
Both worlds are extremely opposite, but… If humanity wanted to move to either of the two in the future, which would be easier to terraform? Are both planets equally optimal for becoming green and blue worlds like Earth?
Terraforming
This is a hypothetical process aimed at deliberately modifying the atmosphere, temperature, topography, or ecology of a planet or natural satellite to resemble the Earth’s environment and make it suitable to host living beings.
The term terraforming itself was first used in 1982, when planetologist Christopher McKay wrote Terraforming Mars, an article for the British Interplanetary Society in which he proposed a method for heating the atmosphere of Mars.
Venus’s atmosphere is so dense that its pressure would cru
ars, by contrast, is an icy planet that lost most of its atmosphere, lacking oxygen to breathe.
None of our neighbors within the solar system are incredibly hospitable to living things. However, on the last mission to Mars, the Perseverance rover managed to convert carbon dioxide (CO2) from the Martian atmosphere into a small amount of oxygen for an astronaut to breathe.
This could be the first step, somewhat modest, but hope for future terraforming of the red planet.
For his part, the famous astronomer and science popularizer Carl Sagan, known for the television series Cosmos, proposed the application of planetary engineering on Venus to make it habitable in an article published in the journal Science in 1961.
They planned to seed the atmosphere of the fiery planet with algae, which would be responsible for quickly consuming CO2 from the atmosphere, thus reducing the planet’s greenhouse effect and making it friendlier to other forms of life.
It seems that both Mars and Venus are excellent candidates to be terraformed, but what process would we use to achieve this?
