Second buck is a shooter all day. From the belly sag and broad shoulders he is definitely an older deer.
The second one is a lot better than what you think. Looks to me like a 4 x 5 minimum and 5 1/2 years old. 150"+ very easy.
I was thinking around that same for the rack. Its just hard to see with the angle. I repositioned that camera to try and catch him walking toward it. I will check it in a month when I am hanging sets in that area. He is a shooter for sure right now so I hope he just adds to his mass then next month or so.
