I have the Walther 400 Alutec Competition, and the Anschutz 9003-S2 Precise. Both are 100% reliable and laser accurate. I have been shooting the Walther for 3 years, but decided to get the Anschutz out of the safe today, and give it some shoulder time. The Precise stock has a huge cant in the stock, and my league now requires glasses while shooting. So I am hoping to get a better head position so I don't see the glass frames.
I like the LG400 loading, and pellet loaded indicator. Both stocks are very adjustable, but the Anschutz in easier to adjust with less tools.
In my opinion, they are both excellent. I can't say one is better than the other.
