What defragmenter do you us?
I use Puran, because I support world peace! 
Does Puran support world peace? No. I just tell myself that for kicks, it makes it more fun, no?
Puran Defrag.
Puran Defrag, no contest.
Depends on your system, i did use Puran on my old systems ( xp, vista ) but defraggler by piriform is excellent for windows 7 as the file placement is the same as the default but it’s faster with separate file scanning, boot defrag, drive health check and temp and numerus other features.

Interesting. I started my carer whit Auslogics Disk Defrag a couple of years ago. Now I have O&O Defrag Free. I might reconsider… 
I just use Win7 one scehduled every day at 1 AM. Otherwise Defraggler though i’m still waiting for it to get automatic defrag mode.
Windows 7 - I use the windows defrag after running the speed test, works for me
windows on Win7
Piriform on XP
Diskeeper.
I have 5 computers and use different versions on them.
Since they run on their own, I hardly ever look at it.
I run Defraggler on both XP and Windows 7.
That’s the old version of Defraggler tested not the new version that is 2.08.373
What was tested is 2.02.253
Yes, it’s a old test. Sorry.
Defragging every day :o a bit of overkill isn’t it ??? with it set to auto i dont think it will defrag unless the system is more than 15% defragged anyway.
Defraggler has auto defrag scheduling in it’s settings.
Defraggler.
Yes
I tried Defraggler once, a couple of years ago, and hated it because it took so long time to defragment. It might be better to day.
It is definitly better today with the new version that is 2.08.373
