Talking about the effectiveness to gain more tickets, playing slot games is better than betting on football matches.
Simply because playing slot games can be done anytime without waiting unlike betting on football matches.
Obviously, it is all about preferences but I have to say that playing slot games is faster but riskier in order to earn raffle tickets.
I think they have tried to make it fair by giving 5x more tickets on the sports betting so it does equalise in both the ways. But I also agree that spending money on slots can give us far more fun than what we could get out of the sports betting. Slots are lively, there is sound, adrenaline and your eyes are wide open when we loose in streak or win.

I think spending the same bankroll in slots will give us more ticket because of how slots was designed to give the player a reward. Besides, sports betting event is very limited while slots game can be played multiple times aside from adrenaline-rising bonus round of slots.
You will indeed get the same amount of tickets but you need to spend 5 times more money to achieve that. So it really is a great promotion especially if you like to bet on football games.

True, as I said the reward system of slots has lots of varieties. Like in every bet we can either get the same wagering amount, or a fraction of it or more than our wagering amount, or got nothing at all. Unlike in football betting where the result is either we get the wins and claim our wagered amount + odds or nothing at all. This also means that in slots, we can easily recycle our funds. It all need is a huge win after several dead spins.
