The one that fits you the best is the obvious answer - but, The gold E does have a stock bolt, and would be my choice if they were the only two guns available.
What do you intend to use it for? the Perennia is a field gun which would be rather light for clays and almost certainly has an auto safety and the X Trap, as a dedicated trap gun, wouldn't usually be an obvious choice for sporting clays or skeet.
TBH. I would wait until you've seem a few more, the right one will jump out at you. If you haven't much experiance i'd again put it on hold until you know exactly what your looking for. At that price range there are hundreds if not thousands of decent guns to choose from.
