Do you play minecraft with mods or without mods?

i mean, it depends, me and some friends have a small smp that we play on with mods, and we have one without mods, i have like mod swings if you will, there are times where i go like 5-6 months without playing with mods, sometimes i only play with mods for a couple mods, nowadays its a bit more balanced, where i play both, but thats mainly due to 1.17 minecraft becoming just as interesting to play as modded minecraft (1.12.2 of course) is. But thats just me, i have friends who dont play on the modded server because they dont feel like leaving the vanilla server yet (we havent left it either, our focus has just been split in two when it comes to smp servers.) theyre the closest to what we have to vanilla purists. there isnt actually anyone who doesnt play on the vanilla server but plays on the modded one, not sure why.
