Can you tell me is gastric sleeve safer or gastric bypass surgery is safer?

Depends: Both can lead to significant weight loss, but severe systemic issues are more likely to occur with gastric bypass surgery. Have a long discussion with your surgeon before proceeding with either surgery.

Sleeve gastrectomy: That's a common misconception by patients. The gastric bypass is a more complicated operation than a sleeve, but the risk of a leak is the same for either operation. In addition, if a leak occurs, it is much harder to control in a sleeve than in a bypass. There are many other pros/cons for each, but the bottom line is that the risk is about equal. For diabetes and heartburn/reflux, bypass is best.
