i was on the Cable and wireless network for a while with ADSL24 and I gave me a good quality connection at a fairly decent speed, considering where I am. I only cancelled to go with a local ISP, other wise I expect I would still be with them.
i would not use the TT network, but maybe that partly because i have only seen one decent connection on their network and also because I hate TT.
Up to you at the end of the day, at least you got the choice.
