I think that most of the people would obviously choose the 150% deposit bonus instead of 100%, because that just gives us more money to wager.
In such a scenario, there is a higher chance of surviving a long streak of losses. It is clear that big part of the people participating in hypotetical survey would choose the higher percentage.

Still, such a bonus gives a lot, but the house edge does not change. It is also important how big is it, because more than 3% is already a lot.
That is why I prefer bonus which basically erases house edge for few hours. That is more interesting, and gives me more opportunities, than having 100% or 150% deposit bonus.
