The self managed versus PM debate is really one of personal preference. I can give you all the pro-PM anti-Self Managed stuff you want, just like plenty of people can do the opposite.
It really comes down to the type of investor you want to be. Being next door will be hard to conceal, and at the same time easier to manage. You can always hire a good PM to place the tenant for you, and then you manage. That will help you with your screening tenants issue.
The most hands off answer is the PM, the question becomes how much you care to be interrupted. The wrong tenant will stop you in the driveway, come outside when you're playing with your kids or sitting by the firepit, and will call you day or night.
The right tenant, you'll never know is there.
The most absolute answer is the PM, and you learning to say "I understand, but you need to call 'David'". You may not advertise that you're the owner, but that's public information, and if your PM will lie if asked about you, how long until he/she lies TO you.
The best advice is to pick what at the end of the day you're the most comfortable with. Give it a timeline, like a year, and then re-evaluate. It sounds like you're PM heavy now, so hire one to place a tenant and manage. If after a year, it doesn't seem worth it, move to a placement only contract. The vice is also possible, start with placement only, and you can always hire to full time if needed.
Good luck!
