Coming back to each bettor's perspective and expertise, both parlays and straight bets can provide value if you are good at analyzing. I personally prefer parlay bets, not that I'm an expert, but I just want more adrenaline when betting. Usually, 3 to 4 matches per week are enough with the small capital I can afford. But of course, in the long run, straight bets provide more opportunities, and indeed, most professional gamblers usually focus on straight bets or moneylines.
