The hardest time in my life was trying to micromanage a large group. Once you let go, and focus on the bigger picture, it's quite fun. Challenging, for sure, but very fun.
I am sorry to hear you have not enjoyed your time leading a large group. It certainly has its challenges, but I assure you it can be quite fun and rewarding.
In all seriousness, I recommend not referring to them as "reports" at all. Call them "My Team", "us", "we". It creates a sense of collective ownership.
When talking up, I use specific names, or "the team" to reference tasks or successes, and "I" when we talk about failures. I own what goes wrong, they own what goes right.
If you fuzzed around with 'my team' while I try to understand you team structure, your direct report count, their profile, which and how many reports they again have, you'd drive me nuts with a fake 'my team' humbleness.
Using the term 'report' is absolutely ok, you shouldn't talk all day long of your reports of course or trying to impressive anyone.
There are very few "rules" in this game, so feel free to manage differently. You have 100+ on your team, so I'm sure your methods worked well for you, as mine have for me.
Management is work. But so is coding. Some people prefer one. Some people prefer the other.
It would be impossible for someone to be CEO of say Google under your logic.
