Sleeves are good for warming up and doing alot of lighter reps, or other movements which require a bit of warmth and compression. Personally I wear sleeves till 200kg, then snug wraps to 320kg, then generally get help wrapping when I go above 320.
Let's clear up some misconceptions about wraps and sleeves.
A proper wrap will give much more safety to the knee joint than a sleeve will, as it will hold everything in alignment. 90% of people have no idea how to wrap properly, or use extremely poor quality wraps, which leads to the notion that wraps are damaging to the joint.
Wraps do not reduce ligament or joint strength whatsoever. This is ridiculous. If anything they improve knee health by providing support for the tendon insertions.
Sleeves can actually cause problems for people because they give the feeling of support without actually providing any(they stretch in all directions) and because your knees feel good you push harder or hit the hole faster. They also can give some people pain because they bunch up behind the knee while the material on the front side stretches. This can cause lateral movement of the knee cap. (This has actually happened to a couple of high level lifters in my PL club and they went to a less aggressive/thinner sleeve because of it)
Some people will not have issues with sleeves, these tend to be people with good leverages/build for squatting and solid technique.
People with longer femurs tend to get more out of wraps than people with short femurs because they usually have worse tendon insertion points. One of the things wraps will do is pin the quad tendon further up which improves the leverage of the muscle.
My recommendation in your case is to do some learning, rehab your injury, then ensure your technique is sound. A good warm up and proper movement patterns should be your primary focus before adding equipment.
That said, everyone should have a good pair of knee wraps. Titan, Inzer, Metal, Pioneer are all good brands. I would get a pair of 2.5m wraps, Titan Signature Gold, Pioneer Lilliebridge, Metal Silver are good wraps that work well in all conditions.
