i honestly think the first one is better. in the first one your overall form is correct, your legs has just slipped back a lot, tipping your body a bit forward. in the second picture you are standing up and leaning over the horses neck jumping for him instead of letting him come to you. not only is that incorrect, but as you start to jump higher it could cause problems because it makes the horse lean on his forehand thus making it harder for him to get himself over the jump and causing him to jump flat.
ideally, when you jump, you should let your knee and hip angles close, not open. to do this you need to only let your body come out of the saddle a little bit allowing your weight to remain centered by letting your butt slide to the back of the saddle.
