Keep them all. It's a great idea to keep all your shots anyway. Memory is cheap, and if you keep all your images you may just find a hidden gem in the future when you look back over your older shots. I know I have. You will sit there and have no idea why you didn't realise how amazing this picture was at the time, but you'll be delighted you didn't delete it.

In this specific case, I'd start by processing the one that looks best from the camera, and see if any obvious problems with it show up as you process that might be fixed by instead going for one of the other shots from the bracket. If you must delete some shots, wait until your sure you've got your finished picture before deleting anything.
