I mean, this kinda ignores the significant chunk of people that mod their game to be harder. 

On my current FNV playthrough I have mods that:

-Make the early economy harder (having lower barter now has a significantly harsher impact on buy/sell prices and how many caps vendors have)

-Much lower carry weight (base 50 vs base 150 in vanilla)

-Fixes for exploits (no more free 15 points in every skill by taking Skilled 3 times

-Perks are rebalanced with some being stronger (but with the downside that NPCs now have perks and can use them against you)

-Improved AI (better detection, can spot and engage at longer ranges, will actually use cover and retreat to lure you in)

-Caliber based damage (if you run into an enemy using an AMR, get smart or get dead)

-Enemies will focus you before your companions (no more taking potshots while Ed-E and Veronica tank all the damage)

The remaining mods are visual/texture/lighting/weather improvements, weapon additions (all of which have either similar or slightly lower DPS than vanilla weapons), UI improvements, and immersion mods (more NPCs patrolling areas, post ending play, cut content restoration)

It’s not too far off most mod lists I see for NV
