One, I like to carry at about 4:30 and the MTAC seems to work its way to 5-5:30 after I've been moving around, sitting, etc. It's also stiffer than I though it would be. It doesn't quite hug my hip like I thought it would. However, I can't compare it to the ST. Other than those two things, I think this is an excellent choice. Retention is good, draw is quick, and it conceals my g30 well.
I just purchased the Minotaur , It is the mtac minus the extra backing I think.(I'm cheap)
I am a big guy and this is the first IWB holster that has worked for me. It is very comfortable and conceals both my Xdm and 1911 very well.
I cant speak to the others you mentioned because I have no experience with them.
