FWIW, what I got was a 15" Dell Precision 7000 series. 7510.
Thicker/heavier, obviously. I'm okay with that. Has an actual proper docking connector for a traditional workstation port replicator. 1920x1080 screen; 4k is an option, but I didn't want that. Screen is matte, which I consider a huge win. Trackpad and touchpoint pointer devices, both with three physical buttons that work really well. Actual key travel, which is also important to me. CPU is 2.8GHz Xeon, it has 32GB of DDR4 and can upgrade to 64GB, so it's got a lot more memory and can upgrade further. Has a PCIe slot for an industry-standard NVME drive, so you can upgrade that if you want, also has a 2.5" HDD bay which you can use for a moving-parts drive or another SSD. Ethernet port, USB-C/Thunderbolt 3 port (it can do the fancy dock thing through that, although that can't power it under full load), thunderbolt 2 port, several USB 3 ports, SD card reader, HDMI port, also a smart card reader. When docked, has actual serial and parallel ports, even. Indicator lights for things like "is battery charging". (I didn't know that was an important feature, until my spouse's 2016MBP stopped working and I discovered that there's no way to tell whether it thinks it's plugged in.) BIOS has configuration options for things like "turn off wireless when ethernet is connected" and such, which is a feature I've had to hack around and emulate on my macs. Oh, and $1,300 cheaper than the MBP I ended up not keeping because I couldn't use it. And of course, the keyboard has escape and function key row.
I dunno about Windows, I'm dual-booting to Win7 for emergencies but basically I run Linux on it.
And it is just such a joy to be back to having a computer with actual expansion and upgrade options, using industry-standard interfaces for drives and memory so I can buy more in two years if I want, with garden-variety screws and no elaborate anti-tampering devices to keep you from opening it. Oh, and a replaceable battery that isn't glued in.
I still miss MacOS, but I do not miss Apple's hardware at all.

The thing about "alternative" is that it doesn't mean "exactly the same". In my case, a much thicker and heavier laptop is an excellent alternative, in much the way that a delicious pizza is a good alternative to eating moldy cardboard.
