Here are my two characters for two campaigns I'm in:
Basic with my long playing group: Lv 1 Fighter S: 12 D: 10 C: 10 I: 9 W: 9 Ch: 11 Hp: 5 To hit: 0 (Thaco 19). Damage Bonus: 0. Ac: 4 (16 in 5e) Stats: 3d6 seven times, drop one number, put where you want. Longsword d8, Crossbow d6
5e with my son who is DMing: Lv 1 Fighter S: 16: D: 14 C: 15 I: 9 W: 13 Ch: 11 Hp: 12 To hit: +5 (Thaco 14). Damage Bonus: +3 Ac: 17 (3 in Basic). Oh, and Second Wind and a Fighting Style. (Stats: points buy + human). Longsword d8/d10, Longbow d8
That's a pretty big difference in basic fighters in terms of ability and durability. I'm having to play the first very very carefully, and the second I'm playing as a Noble, using his wits more than bashing everything, trying to be a mounted "knight", but still able to fight off several creatures at once and survive.
Over the 4 decades I've been playing, more and more has been added to both the game, as well as to PCs. I'm putting that down to catering to folks who want "moar power" and "moar options and choice", even though the choice anymore is more illusion than anything (table differences excepted). We played 5e through Tiamat and Storm King's Thunder, and by 8-10th level the DM had to go waaay outside the written adventure to even cause half the party to break a sweat. It was anticlimactic and unsatisfying overall.
I'm having way more fun DMing Beyond the Wall, playing in Wolves of God (Historical Britain), and playing a fighter (the only PC in my "party") in my son's game, where my son is doing a bang up job with places, names, NPCs, interconnected plots, etc.
Though I am concerned that my son will be overwhelmed if I select Battlemaster at 3rd level, since it will up the relative power of my character, and may be too complicated for him to be able to manage. We'll see. That third level for every class in 5e adds unnecessary levels of complexity, IME.
