Thank you guys. Seems that Shimano has a higher reputation. It performs better because the weight or because it's more durable or other reasons? And seems 105 will be a better option for daily training and racing. What factor of derailleur affect mostly to the performance?

Thinking of change a derailleur set for my current road bike, Which one should I choose between Shimano Ultegra and SRAM Force ? or do you have other recommendations ? What factors should I pay attention to ? BTW, has any one bought a Campagnolo? way out of budget and hard to see in the market...
