The sense I have is that you may be under the impression that admission will be easier to physics than engineering physics. Though the physics major is in the LAS college, the physics department that controls it is in the engieering college and follows its admisison criteria, including that the middle 50% range of those admitted to physics is more akin to what you see for the enignnering college and not that for the LAS college. In other words if your thinking put physics first because it is easier to to get in, you would be incorrect.
Though the two are similar, engineering physics diverts from regular physics in the junior and senior year when the enigneering physics major gets to pursue a chosen concentration that can be a more prcaticable application of physics and can include another engineering concentration such as computer engineering. In other words, it can be used to pursue course work that can lead to employment as an engineer, and it results in a true engineering degree. Nevertheless, what you choose now can be changed later as long as grades are decent. Engineering physics could have some slight advantage because admisiion to it includes the possbility of getting scholarships offered by the engineering college which usually has more to offer than the LAS college. However, unless you are in the high end of engineering admittees, you should not expect much, if any, scholarship money.
