Which tooth is better

[Sergiorex]

I’m thinking about buying one of them, assuming their the same price which one is better? 
my general overview- tooth in matrix is smaller, only .75 inch. But higher quality. However It can’t be id, it can be either Nanotyrannus or trex

the other tooth is significantly bigger but has more wear and is confirmed to be trex. There’s no picture of bottom but I asked for one and ofc if they send it and it’s not a trex tooth I’m not going to buy it.

I don't see a picture of the root or county on the first one.  I've seen that tooth before and whats on the webpage in regards to formation doesn't match whats on that label. I'd be cautious labeling it anything considering that.

Just an fyi the first tooth has its enamel missing on one side and a portion of the base.  The tip is a different color and may have been reattached.  The second tooth looks perfect.  So from a quality standpoint the second tooth is much nicer by a mile.    The first tooth if its from SD the HC is the only late cretaceous deposit in that state.

Can confirm, if that's the listing I think it is, the webpage description says Judith River Fm. of Hill County Montana, but the label in the photos says Hell Creek Fm. of South Dakota. A bit concerning, I'd ask the seller for clarification.

Yes thats the one.  Assuming all equal though, I agree with Troodon 100%. 2nd tooth is very nice on the matrix.
