Its a dangerous thing asking for views on a selection of rifles on web sites as it usualy induces lots of personal views some of which, and often all, are worthless.
I coach various shooters and have seen and have experience of most rifles, the difference is preference and set up, the Anschutz does not have the best trigger but with good set up all are superb. I think you can see from what I have what my preferences are but I know well that the others are just as good. All are used at top level and a look along the line at big meetings will display all. A good guide is look on the ISSF website at the videos of the world cups and you will see them all and how the different builds have set them up. You should also consider the FWB 800 and the Pardini GP1, but the only true way to decide what is best for you is to look at and if possible try them all.
Good shooting
