All the devices you listed are 3g so you would be getting the same data speeds as the HD2 will. I'm currently using a MyTouch and like the way it functions for the most part. Being that it is all touchscreen it can help with the transition to having no keyboard if your used to having one. The Cliq XT just came out last week so I haven't been given any feedback from customers yet but I do know that the cliq is the most popular android device for TMo these days.
