I don't know if DNF's is better, but yum tracks groups too - it was 
about the last major feature added to yum:

https://fedoraproject.org/wiki/Features/YumGroupsAsObjects

An important note, though, is that no Fedora release so far has 
written the groups installed during installation out to the installed 
system. That is, when you install Fedora Workstation 21, neither yum 
nor dnf will know the 'workstation-product' group is installed (unless 
dnf infers it somehow, I haven't checked).
