As said before the hex reciever is a little bit more desirable to a collector but we are not talking about a wide margin there. There are hundreds of other things that matter way more to serious collectors than this. Different markings, older ex-dragoon models, rare dates on certain type Mosins from certain factories. etc, etc. If I wanted this gun as a shooter then the condition of the riflings in the barrel and whether or not it had been counterbored would be waaay more important to me than hex vs round reciever. In fact the general outer appearance of the gun would carry more weight with me than what type reciever it had. But if all other factors are perfectly equal then sure, get the hex reciever.
