Standard 4D or 4D HD Live?

Struggling to choose lol. I found two deals. One is a standard 4D 10 minute scan that includes 3 6x4 images, one A4 image, the whole thing recorded on dvd, and all images on cd for £80. The other one is a 4D HD live 20 minute scan that includes 2 6x4 framed photos, all images on cd and growth measurements of baby for £85. Which one would you go for?
