There's been a lot of talk in the last years about a trip to Mars (with SpaceX having the most serious intentions). I can understand that it has a less harsh environment and it will be easier to land and take off from the surface due to lower gravity, but Venus has lots of advantages too!
Lower on Mars - easier landing and take-off, lower energy consumption for everyday operations.
On Venus almost same as on Earth - potentially MUCH healthier for humans. This single feature could outweigh all the other advantages on Mars in long term.
Environment (atmospheric conditions)
Milder on Mars - easier to build reliable housing and suits for outdoor activities.
Harsher on Venus - because of temperatures and acids in atmosphere probably classic suits won't be enough. Will probably need to design mecha-like, exoskeletal-assisted vehicles https://static.squarespace.com/static/51b3dc8ee4b051b96ceb10de/51ce6099e4b0d911b4489b79/51ce6197e4b0d911b4499697/1303346867025/1000w/Heavy_Mech.jpg. But nothing an engineer couldn't do these days.
Much less energy from the Sun on Mars (because farther from the Sun).
A hell lot of direct solar energy on Venus, plus the environment is so hot that there is no need to use solar panels. Just put out the turbines and they will run on the hot Venusian air.
Mars probably much easier to terraform than Venus (I mean mainly the atmosphere). But in both cases this procedure is so long-term it doesn't really matter for us in the near future.
Probably different amount of different resources but still same overall potential on both planets.
Further space exploration
A bit easier from Mars because closer to other planets (and the outer bounds of the solar system).
