it depends how do you define good. many of my clients use ubuntu, my team help them to manage their servers. we did not see problems, no problems is good or higher performance than other platform is good?

Well I loaded Ubuntu 14.05 lts server along with Sentora control panel and I have learned a lot sure am glad I remembered old DOS it helped me a lot to learn the commands that Ubuntu uses. Everything is running great and it took care of the problems with the website I was having while using Windows Server 2003.
