From a safety point of view it's much easier to find lost a/c with SSR.I have seen it numerous times,including one that got lost twice in the same area within 20 mins.
In our area we will ask you to squawk,identify and give a FIS.We have a lot of Military that tank around under the CTA,and SSR is invaluable.
If ModeC is used, it cuts down on the TCAS alerts,vectoring a/c over the top.
At Aberdeen we are not a LARS unit,but give a service subject to workload,which is often considerable.
