Mine have changed somewhat. I have dropped SaS and replaced Auslogics Defrag with Puran. I'm concerned about Puran though since there hasn't been an update in a long time and my emails to them go unanswered.
The fact that it hasn't received any update for some time can tell you other things, A) that these type of programs don't change much once you have the defrag algorithms, etc. and probably only changes when OS versions are added or changed B) that it is relatively stable and bug free.
What you have to ask yourself is it broken and does it still do what it says on the tin, for me it isn't broken and is a fine defrag program, that I have never had the need to contact support for the free product.
The support side is another issue entirely, I don't know if that would change if you had the paid version.
