Fellow Note 5 Users Opinion needed on the N920C Model

[nokia4life]

So I currently have the N920i model which works perfectly on ATT all bands are working just fine LTE is there and everything. My question is I am going to buy the N920C for a family member graduation gift. Based on my research this model unlike mine actually has the exact same bands as the ATT model plus like 6 additional bands. What I want to confirm is if anyone here has used this particular model on ATT as I just want to be sure since the model that I have also international works fine but for some reason it cost more than the C model by about 10 dollars USD. Yes I am being cheap lol.... not really still a helluva gift. Thanks see below on comparison notice how the 920i is missing band 20 but works fine for me.

AT&T Model - LTE Cat6 700/800/850/900/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5,7,8,17,20)
N920C Model - LTE Cat6 700/800/850/900/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5,7,8,12,17,18,19,20,26)
N920i Model (my current) - LTE Cat6 700/800/850/900/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5,7,8,12,17,18,19,26,28)

I guess I should have been a little bit more clear. I have already been to that site my question specifically revolves around band 20. If you notice above I list out the models the two international models and the one USA model used on ATT. The only difference between that ATT model ending in A and the one International Cambodia model ending in C is the addition of bands 12,18,19,26) So I am buying this as as gift for someone and the model that I have is just the International model ending in (i) doesn't have the band 20 and it works fine on ATT, but the one ending in C has it but is way cheaper (Price) so I was asking if any one knew what Band 20 spectrum is and if it is really used by ATT consistently thats all.
