I've used several brand of climbers over the years, and I would choose the Lone Wolf over any other I've personally tried. Great stands. High dollar, but worth the extra money IMO.
If you're looking for maximum versatility, you might want to consider a lightweight hang-on with a set of steps as well? You can get up "less than straight" trees better with such a setup.
I bought the LW Alpha and sticks for just such reasons. There have been times I skipped a good looking spot because I couldn't find a "climbable" tree. With the hang-on+sticks, that's less of an issue.
