Hi MrDrem,
Well, since you asked, we make the second one (the Torc Series II anchor), but the first one (PJB's Concave anchor) is also good. We can supply the Torc with a specific fitting kit that allows you to set it into fresh concrete (so there is more metalwork than you see in your photo, as well as different fixings to hold it all together - PM me and I'll give you a link to our web page that details the range of fitting kits, with more photos).
The Concave has the advantage that it is truly flush when it is installed, until you put a chain through it and then none of them are flush ;-) The Concave can trap water in its 'U' bend, and although there is usually a drain hole (that should be positioned below the concrete), such things tend to get bunged up with leaves etc after a while. That is pretty minor as the security of your bike is likely to be more important than whether the chain gets mucky or not.
To be honest, it can often be what each supplier also offers in terms of Package Deals etc as there may be more difference in terms of chains and locks and other products. If you can get what you want from a single source, you can potentially save on shipping.
Feel free to ask more specific questions if you like.
