"Best fit" is my entirely subjective way of saying that I want another meter with similar accuracy and build quality compared to my 287, but would rather not have two Flukes. Seems better (to me) to have a different meter entirely, with perhaps different features, as a sort of adjunct the the 287. I suppose I'm looking for a non-Fluke counterpart with accuracy/build quality/general feature set comparable to the 87V. If you have other suggestions, I'm glad to hear them.
I'm with Lightages here, you would really do yourself a favor and take a long look at Brymen.
If you're still interested in Keysight, the U1252B is better suited for electronics (and a direct competitor to the Fluke 287/9 series). The Brymen BM869 is also comparable with the U1252B & 287/9 models, but can be had for less (
TME's BM869 page here).
Brymen's BM25x (257 in particular), BM52x, and BM82x will be closer to the 87V, with some extra/different features (i.e. do you want logging or not, and so on). The BM85x series is the predecessor to the BM86x series (no dual display, and the backlight is different).
