Hi CaosCompleto and welcome to the Q&A Forum.
I don't think it's a matter of which is better, but which camera has the features you want most. If you're happy with Olympus, stick with it. They make fine digital cameras.
Similar cameras to consider are the:
Panasonic DMC-ZS3 10MP with 12x Wide Angle zoom

http://www.digicamhelp.com/amazon-store/?apid=B001PKCJYEThe Olympus Stylus Tough-8000 is in a class by itself compared to the other cameras. It's waterproof, shockproof, freezeproof, crushproof and shakeproof. A drawback may be that it only has a 3.6X zoom, though the other features may be more important to you.
