none of the above, although you didn't really say what you were going to use the toy for, personally I have my eye on the Tantus Large Ripple for my next anal toy purchase (or for those that are still beginning, theres the smaller version of the same product) which looks to be a very good toy for not only stretching the capacity of the rectum but for using during masturbation as well....
now if you're looking for long term wear items I'd recommend the stainless steel njoy plugs (the larger sizes) which will all last a lifetime, look beautiful, and many of my friends have told me I must try them (quite low in the cash department these days and EF's 15 dollar shipping charge (and thats to START!) to Canada doesn't make things any easier either.
although I'll agree with others on this one, out of the ones you chose I'd say the ripple is your best overall bet for a stationary 'long term' toy, or the anal tool if you're looking for a thrusting anal toy.
