Even if I am not familiar with its latest release, Plesk seems to be better and better.
I was used to work with it 5 years ago and everything was all but absolutely not secure nor stable.
Then we switched to Ensim. (What a mistake!!!)
Each upgrade was not for the fine of heart.
We hated it. Their support was simply unexistant. Their advices unrelevant. Fix were coming weeks, and sometimes months, after the issue. Hopefuly, the customer's community, through their forum, was pretty helpfull.
Disgusted, we switched to cPanel.
Since SWSOFT acquired Plesk, many improvements were done and now it looks like a mature program. Even if I am still using cPanel (and loving it), I may try Plesk in a near future.
