There is no definitive answer to this question, but there are pros and cons for each one. The female matures earlier than the male, in fact she can already go in search of the truffle bringing good results from the second year of life, instead the male from the age of three. The female is certainly more tame and balanced, even if, in case it was not sterilized, it can cause some problems when for example it goes into heat (they have two heat per year on average). Males on their side may not be so obedient and run away if they feel the presence of a female in heat. In any case there is not a sex that is better than the other in the search, they can both learn very well this activity and give a lot of satisfaction to their master.
