Many people make preferences based on their experience. If I have had the most luck playing dice and won there much more often than in slots, then I will choose the dice to play in the future. If someone on the contrary has won more often in slots, they will give preference to them in their choice.
I go with you with that, if you find more luck playing dice and able to work with some strategy that you've created then
choosing dice will be a go sign for you,
while same thing with slot, some find this as much better since when you hit the jackpot the winning amount will really gives you a huge benefits.
A jackpot win is like throwing a bone to make it stand on an edge. Personally, I choose games that I like to play more, and not where there is an opportunity to earn more. However, all people are different and I told how others can make their choice.
