When referring to the prize amount, yes, progressive jackpots are better than fixed ones since they not only run higher; they are constantly growing. To pick which to play, you must decide how you want to win. For the largest wins available, look to progressive jackpots. These take a sum from every bet of every player and add it to a high jackpot amount. They vary in size at any moment though they take time to win. Fixed jackpots may be won more frequently, though their prize values never change. There is no answer as to which is better, as it remains up to you!
