I use Synaptic Package manager all the time, and prefer that over the Software Center (not even installed now). There is nothing wrong with the later, but its probably a personal preference.
One feature I really miss though is a clear button on the quick search box. I think it is easy for you guys, and would turn my life a lot easier.
Thanks for your attention
Great distro by the way. Using Linux from 2007, and besides the first year with Mandriva, and after trying some others, I am Linux Mint all the way. (currently using LMDE)
