I chose a border because I didn't think the full bleed suited some of the images. It would be useful if you could control the layout of each page rather than choose between options for the whole booklet, though I recognise that this may effect the costs.
Print quality is - OK. At optimum viewing distance (the distance across the diagonals), it's good enough. Get closer, and you can notice the resolution. But it does vary from image to image, and I have to say that for the price, it's very good. I'm just used to hand printing my own images to a high standard, so I am very fussy.
Apart from the aforementioned colour casts on some of the black and white images (which aren't necessarily disagreeable) colours are very faithful. This was a relief to me, as I am very fussy (I'm having immense trouble scanning slides satisfactorily at the momenet, and I haven't really taken enough time out to calibrate my monitor properly).
