Despite being on the same level, there are large differences between the 200 level endzone seats and the 300 level club seats.
First, you won't have access to the same amenities that club ticketholders will have. You also won't be able to exit and enter the section at the top - so you'll want to choose a lower row if you expect to head to the concourse a lot. Finally, the views from the endzone are just OK when compared to corner and sideline seating. These sections do provide more elevation than the 100 level seats, so seeing the other side of the field is easier.
