We could just repeat the verdict from last year's model at this point, because not much changed with this update. The new Kaby Lake processor is a bit faster, but the GPU performance did not change.
excellent chassis and build quality; huge trackpad with great precision; quiet and good cooling; high WLAN transfer speeds; very good display with perfect scaling; good speakers; good battery runtimes; steady performance; also on battery; 4x Thunderbolt 3..
...but reduced bandwidth for the ports on the right side; neither USB-A nor HDMI-out; 2.4 GHz WLAN issues with attached USB-C device; poor webcam; very expensive – especially the upgrades
