Squats are better in terms of risk but it does depend a bit on your anatomy. If you're super tall with long femurs, you'll struggle to squat without leaning forward at which point the risk profile is close to but still not as bad as a deadlift.
Also don't fall for the "ass to grass" meme. Many male hips just cannot physically do this due to the shape of our hip sockets. Squat to a depth that you could pause at if you had to.
>safety bar?Safety bar and trap bar are the ideal for squatting. Safety bar vastly reduces the spinal loads as you don't have to lean forward. However, you need to be confident squatting using a very upright technique - look at how olympic lifters and Tom Platz lift, their chest is up and their knees come forward. This of course means the knee loads are higher though.
Bear in mind that intensity is still the key factor. safety bar or not, you need to be taking it easy. Any weight you choose should a) allow you to pause at any point of the range of motion and b) allow for >8 reps.
A basic rule of rehab is that you'll have to start with low-ish weight and high reps until the strength returns and pain fades. Most of my patients are starting in the 15-20 rep range and don't get down to 8 until they're at about 70% capacity.
