My work laptop is a 2017 15" MBP. I was able to get a 4k external monitor and it definitely felt sluggish. That's when I realized the $70 multiport dongle that apple sells cannot do 4k at 60hz, and so I was seeing 4k 30hz. Had to get a dedicated Displayport to USB-C cable and now it seems to be fine.

I haven't had too many issues with performance. Few crashes here and there. The keyboard is more of an issue for me when dust gets under the keys. I don't mind the giant trackpad as I feel it gets palm rejection right most of the time.

By far the worst part of this computer is the touchbar. It's useless. I can't fathom what Apple was thinking making this required for all higher end Macbooks. The only thing I use it for is the volume slider, and occasionally buffering songs on Spotify. Other than that the ESC key is horrendous and it has no utility for me over standard keyboard hotkeys/fn buttons.
