These to me are different concepts.
As they are to me as well.
The brand I trust most to deliver what I can live with — in a good way, and not as in, "I 'trust' Pelikan's M40x EF nibs to be all over the place, from one nib to the next, in the line widths and wetness they put down, but they will all be 14K gold and screw into M40x and M20x pen bodies perfectly" — in factory condition, consistently and reliably, is Sailor. I can look at its marketing images of any Sailor model above $30, and trust "blindly" that if I ordered a unit of it, the colour will not be significantly different, the finish will not hold unpleasant surprises, and the nib will not (i) be scratchy (such that it 'catches' fibres on the paper surface or rips through the paper coating), (ii) leave too wide a line for the stated nib width grade, (iii) have either misaligned or asymmetrical tines, or (iv) write either too dryly or too wetly for my tastes.
The pens I enjoy writing with most, out of what I already own, are Pilot fountain pens: the 'Hannya Shingyo', Capless Vanishing Point (specifically in matte metal or resin-impregnated birch finish, although I do love the look of the Capless raden VP pens I have), Elite 95S, and Justus 95. However, as a fountain pen brand, I like it least out of the Japanese 'Big Three'.
The brand I like (or want to like) most, out of the Japanese 'Big Three', is Platinum. It offers the Slip-and-Seal mechanism in even the cheapest Preppy model, and that's cheaper than any Sailor or Pilot fountain pen — but I don't trust its nibs to perform consistently in terms of line width, from one nib to the next. It offers the cheapest (brand new) solid gold-nibbed pen with the KDP-3000A. It does the most variations with its 'flagship' product line, the #3776 Century, and presents models in acrylic, celluloid, ebonite, different types of wood, kanazawa-haku (gold leaf) finish decorated with traditional drawings, etc. quite unlike what Sailor does in its dozens of "special" and/or "limited" edition models of its Profit (aka 1911) and Professional Gear product lines only in different acrylics. (Sailor's "Precious Wood of the World" series, based on the Sapporo model, is the one I actually dislike even though the nibs write perfectly OK and still perform to expectations.) Platinum's Izumo line, fitted with 18K President nibs, are good pens too even though I had to fix a tine misalignment issue on my Izumo aka-tamenuri myself. Personally, I think (or feel) Platinum tries the hardest. And its Balance line of pens disappointed in that the caps aren't that effective at preventing ink evaporation; whereas I never had the same issue (or to the same extent) with any Sailor pen that I can recall owning, including those cheaper than the Platinum Balance. Pilot pens >$70 have been pretty good too, in that regard, but the MR (Metropolitan and other ranges) and 78G pens are apt to dry out when capped and unused.
I have more than two dozen pens in each of those brands, and that's too many to bother listing individually.
