I'll be honest and say as I'm really busy right now, that I've only read about the first 5 posts, but here's my bit...
Over the decades, I have finally settled on Ilford HP5, having tried it in both 35mm and 120 size, in various slr's, MF, point and shoots and most recently Kodak Box Browies.
The films have been developed in various developers, to see what they all offer, but having used it in the past and again right now, I will be using ID11 / D76 @ 1+1, as it gives me a good tonal range, unnoticeable grain and good speed for our lovely changeable UK weather.

Any lab should be able to offer it to you but I don't know if it's been mentioned, but scans of films from labs are very hit and miss. I'd suggest going for the highest scan res that they can offer, and see if you like the results. If not there are plenty of other labs out there to try, including Ilford itself, who out of everyone should know how to develop their own films well.
As a final thought, I've also used and like XP2 very much. I had the film developed at Snappy Snaps and a good job they did too! It should be noted that I print at home so don't ask for scans the occasional time I use this film.
I'll try to read the other posts later on.
