I work in a mixed age environment.
I'm Gen X and I love boomers. I just love them. They tell you what they think, what's wrong and what's a good idea, and they don't care whether you take their advice or not. They will give you a nod when something goes well and shrug their shoulders and sigh when it doesn't, saying things like "Well, I did say it might do that, Torunette."
Millennials are a nightmare. Half of them act as though they drink way too much coffee, which they probably do, and they seem to burn out quickly (probably because they are so hyper) and then want to chuck it all in and move onto something else. The other half seem to be very fatigued by life, as though it's all fallen very short of what they expected. Life is to be "tolerated" in the same way one might tolerate a particularly hideous rug in your living room. A lot of them remind me of Eeyore.
I don't come across a lot of Gen Z; my field is probably too old for them at the moment.
Gen X, my own generation, is the weird generation though. All of us are strange and not particularly similar to each other at all, probably because we were ignored by the boomers when we were young, and dominated by the boomers in the workplace in our twenties and thirties, so we just went off and developed our own strange habits and interests. We are the Un-Generation.
