Every new version brings both the good & the bad.
Personally, I'm not a fan of the smarter villagers. I like to create huge villages, sometimes cities. Villagers will now wander out of town, endlessly looking for work stations & beds & town bells. If you have any legacy version maps or megavillages generated from a few lines of code added to custom superflat worlds (RIP), then you have to go in & add all of that stuff. It could take forever.
The code to make villages spawn closely together in great numbers no longer works. & I wan't particularly happy when villages started spawning with solid foundations under the buildings & paths, because I got a kick out of terraforming disasterspawns into functional multilevel towns with lots of stairs. However, when they spawn over water, this is the one time I like the change.
They're pretty old by now, but I never liked the golems. They spawn in ridiculous numbers in player-made villages, get stuck on fences & in between tight spaces. They're always in your way when you're trying to build. They are 100% useless in Peaceful & should not spawn if enemies cannot spawn. The bug fixing team has been trying to fix their spawning problem for years.
I hate the dolphins; they eat all of the fish in my ponds & aquariums. They keep bumping me when I'm trying to build underwater.
I hate the wandering trader. He's always invisible & getting his llamas stuck in doors, & they make the most godawful irritating noise. He also constantly gets in my way when trying to build. & unlike the villagers, he doesn't take a hint after being punched.
I am not looking forward to the termites that were announced. I hope to god they do not spawn in Peaceful. That sounds like a builder's nightmare on par with Creepers.

On the other hand, I'm a huge fan of all the decoration blocks they've added over the years. There will never be enough different types of slabs, stairs, & doors to sate my taste for variety, though making colored concrete or terracotta varieties of all those things would definitely thrill me.
I was super excited when all of the new biomes & trees & flowers came out. Hope we get another round of new biomes & plants in the future. Looking forward to the new baobab trees.
I love all of the new passive mobs. They make the world feel less desolate & quiet. Not that the rabbits make much noise. Looking forward to the new ostrich mob.
I love all of the new crops.
I like that armor stands can now hold non weapon items like the picture frames do.
In newly spawned villages where I don't have to spend hours & days adding workstations & beds & bells, the new villager behavior is perfectly fine. It's rather amusing watching them trade with eachother, because it often looks like they're having a food fight.
I like that cats spawn on villager beds. They should have their own dogs spawn in villages too.
Having spent a lot of time in 1.7, 1.8, & 1.12.2 recently, I have to say that 1.14 has less lag, renders a helluva lot faster, has less lighting & shadow issues, & I'm pretty sure flying 7 sprinting is a little faster too.
The oceans look infinitely better in every possible way now.
