In most cases it depends on what mics you run and what you keep the rest of your gear in. If you have very short mics (KM184 etc) straight female ends often help get the mic far enough forward in a mount like an AT8410 so you can get a good sized windscreen on whereas a full length mic (Nak 300, AKG480, etc) often benefits from a right angle connector for keeping the cables closer to the stand. On the other end, if you run your pre or all-in-one in a tight bag, right angle male connectors often allow a smaller bag (a Nova 3 or 4 instead of a 5 for instance) to be used. Then you also have the option of custom RA stubbies. If you run with the equipment out of the bag, then straight connectors may be easier to work with. Besides what connectors you want, there is also the matter of what brand, type (material - copper, silver plated copper, two conductor with shield, quad with shield, etc) and size of cable stock is used to fabricate the finished product.
There is no general rule on ends other than use what works well for you and your particular setup.
Of those TS cablemakers linked, any of them can make a set you would have no problems with. As far as prices, turnaround time, etc., get in touch with some of them or post what you're looking to have made and ask for them to send you prices.
