I had the same question and I was told "Bright Nights", apparently?
Anything but version 0.G
I eventually liked Nested Containers since it allowed you to drop cargo before a fight and it made inventory management generally more exciting (was much better than the alternative of pushing a shopping cart around everywhere).
But the continued gutting of CBMs/Bionics and Science-Fiction in favor of "Realism" was silly given the initial lore/premise in a Zombie/Lovecraftian survival Apocalypse.
Also not a fan of the implementation of Proficiencies and Weariness with regards to crafting; it's unfun and an artificial annoyance to slow down the game. They should've just focused on adding more/harder content instead (like expand the crafting/tech tree to include futuristic stuff you could craft to combat futuristic enemies, like better Power Armor, custom CBMs and crafted beam weapons).
Sometimes I go back and play 0.C back when you could craft a Pneumatic Rifle. That was fun.
Also the Magiclysm mod is pretty cool and adds some spice/options/threats to any version. Though it continually suffers from balance issues (e.g. getting instantly mauled by a super fast Owlbear or Troll; or taking down
this bitch with 5600 HP (Distance + A LOT of .50 cal ammo)).
I love the Translocator Gate that allows you to teleport between multiple places/bases. Way better than the Fast Travel feature they implemented in the Overworld Map and well worth the effort to eventually build that network of tele-gates.
Also I feel less compulsion to use Debug menu teleporting to conserve my real life time.
