Which is better getting paid a base salary of $115K or a base salary of $105k but get bonuses that add up to $115K?

So I have 2 jobs offers one is for a base salary of $105 but they will give bonus each week to where I will make $115K a year. The other offer is just for $115k a year and thus I was wondering is their a benefit to one over the other in any way.
