For a while, I had both auslogics and IoBit defrag programs on my system. I had used Auslogics for quite some time (like years - not days). It was efficient and fast but did not have the optimize and "shut down" the computer when done options. So IoBit was on my system for those features. So I would run auslogics for the most part and would run smart defrag occasionally to take advantage of the optimize feature. The new Auslogics has included an optimize and a "shutdown" after running (for the cleanup and clearout crowd). Ergo, I removed IoBit smart defrag and still remain faithful to auslogics defrag. Try it - you might like it.
Is the best defrag,
