O2/Be LLU or Sky LLU.

Probably O2 if you have an O2 phone, Sky if you want Sky TV.

...... But yes, I also download a lot. Definitely no download data caps...

That rules out O2 then.

True.

Be is the alternative to Sky now, not O2, but SKy is cheaper.

Locally, a lot of households use Sky TV because of the topography of the area and the resulting poor reception of Freeview. Sky have a pretty extensive LLU coverage here so the broadband is peanuts. This, along with the obvious attraction for the "download the internet" brigade, the Sky network is starting to creak quite loudly.
Although the service is on the whole, still very useable, it seems that Sky's policy for now at least is to sit tight and let users "slug it out". I can't help wondering just how long this "all you can eat" bravado will last. Given that all the profitable exchanges have long been snapped up with the inevitable tail off in "new customer land grab" lockins, a (Probably small) bleed to FTTx and mobile services and a gloomy looking financial future, I think that Sky will soon be following O2 down the belt tightening route.
