I don't, really. I mod other games, but Sims 4 was never really a candidate in my mind because of how troublesome it is. I even gave it a shot and removed them right afterwards and scrubbed the saves.
It just depends on how much effort it is worth to you. In my opinion, 4 isn't really worth it with how many updates and DLC packs we go through without a Steam workshop equivalent (though there are some really nice options out there). However, there are games I just do not play unmodded.
If vanilla is easier, no need to force it. You can always find current mods when you have an itch to scratch in the moment and remove them later instead of trying to maintain them all.
