This is my "main squeeze" out of a lot of machines, this one is in my living room with a big-screen TV as the monitor.My 4th gen NUC finally just died - I'd "rebuilt it" a couple of times due to the heatsink grease creeping out, but was happy with it.  I didn't give it stars for storage, as these don't have any - you have to but it separately.  The main difference I notice is that the NVME drive and ram I put in here are a lot faster than the msata and ddr3 in the 4th gen box.  As far as CPU...well, there might be more transistors, I'm not counting, but when you push it to say, render video or some other tasks - might as well be the old one other than storage limited things are noticeably faster.  OK, so you're not going to game on this - the graphics are actually not so hot - and it's not that fast. But it is silent, plays youtube with video tearing only if there's motion....and doesn't waste watts - critical here as I'm off grid.  I have 3 working NUCs, the other two 4th and 5th gen.  They are reliable...I like the tiny box...(I run linux, FWIW, no issues there).
