Only downside ive seen with Debian is slower rollouts and some packages missing in their repos. Its because they prioritize stability.
If Debian fits your use case theres no reason not to stay. I ditched Debian after I accidentally created my frankendebian monster which i was way too unknowledgable to save back then.
And hey, welcome to Linux!
Good colleagues make it bearable at best. Was stuck with that for 5 years. Would never work for those people again, no matter the colleagues.
