Since it's your money I say spend it. What row are you in 107?
I think the lower level has a pretty shallow angle and if you get too low, the view gets comprised. If you're toward the end of the alphabet or double letters for the row, those are high enough to have good view.
For several Steeler games, I've sat in the 200 level but in the end zone and they are normal seats. I did sit in the endzone club level in the NC sections once and it's a standard NFL club section.
The 200 level on the sideline are also club seats so you're in a seat outside but have an enclosed lobby area with upgraded concessions, restrooms, AC, etc. Never sat there but it seems to be a pretty typical club seating area just like the NC sections in the endzone.
I think the 200 level is at a great vantage point, not too far from the field but far enough you have a good view of the entire field.
