Surely a far harder target for success than Mars. It's a bit of a mixed bag and if you pop a level up on the linked site and go through the various probe pages, you'll find discussion of many of the issues. One mildly counter-intuitive difference is that the atmosphere on Venus is so thick you can parachute/freefall probes onto the surface, landings on Mars are 'harder' in a very literal sense that's waylaid many Mars missions.
