I use daily both Fedora and Ubuntu. For security reasons and for Linux defragmentation-agenda-reasons, I recommend Fedora and also use it in my home computer. Ubuntu and Debian should transfer to rpm package format and overall should more closely follow LSB-standards and -recommendations. There is well argumented technical and political reasons why. It would be beneficial for the whole Linux ecosystem to have more compatibility between distros, at least on the lower level. Microsoft is happy Linux ecosystem is so scattered and fragmented.
