i would say there equally dificult for a begginer the best way to do it is to find someone that has done either of them before and ask them to show you how to do it popping in my opinion is alotharder because of the fact the most of the time the male will hold back his hemipenes witch could cause problems like most of the people on here are talking about. but probing you have to buy probes wich i can not seem to find online.
well good luck,
