I really don’t get how anyone can think higher stats are a big deal in 5e. They don’t make that much of a difference.
Seriously, give every PC a 16 before mods, and play the game as normal. The difference will be somewhat noticeable at low levels, and you won’t notice unless you’re actively looking for it by level 8 or so.
The only major impact is more CharGen freedom. As someone who has started (after mods) with 15s in Dex and Int, 13 Con, 12 Wis and Cha, and 10 Str with one character, and another similar character started with 17 Dex, 14 Int, 14 Strength, 16 Wis, 15 Cha, 15 Con, the extra HP from Con was the biggest difference.
Ive played with PHB point buy, 32 point buy, 4d6 drop lowest reroll 1s, choose between two sets, and 10+1d6. In 3.5 an oddball DM I knew used d4s to roll stats, because they gave a “better distribution”, but no one else I’ve ever met did that, and I haven’t tried it in 5e.
Anyway, all my games have run the same with any of those, except that weird concepts are less frustrating to put together with the more generous options.
But I’d choose feats. MC builds are harder to deal with, and point buy works fine. But I only consider 5e satisfying in terms of breadth of options with feats.
