Zoloft vs Rexipra which is better option

I was smoking weed and cigarettes for 3.5 years and I stopped it 1.5 years ago but relapsed cigarette after 8 months and relapsed weed since a month and I've been diagnosed with ADHD,OCD,PTSD,BPD by various psychiatrists over time so I believe I have them in various levels. I also got depression,thanatophobia,anxiety (severe sometimes) and panic attacks. I seen 7 docs and 5 therapist regarding all these and a doc who served as a Professor in London Prescribed me an SSRi called Zoloft 50mg (Sertraline) @Morning for 3 months course twice but I failed to complete course twice and I'm undergoing psychotherapy too now my therapist recommended medication so I seen another normal psychiatrist and he prescribed me with Hope 0.5mg (Clonazepam) and Rexipra 15mg (escitalopram) @night for 3 weeks and I started that course today after stopping weed. I'm confused which treatment to continue when I think of the fact that one doc is way better qualified than other. So please answer which way to choose
