How about beeing more specific on what you hated on the gens you didnt like, Then we can tell you if its the same or not.
The game is a pokemon game with 3D graphics, and includes good poekmon training tools if you want to go pro that dont involve having to level a pokémon from sratch. You can pool your EV's however you want. If you dont care about that, there a bunch of cool pokémon.
I cant comment on the story yet because i have been enjoying too much getting lots of pokémon and using the GTS to trade pokémon so i have the ones i like early. I have charmander, squirtle and bulbasaur and i only have 1 badge. Gen 2 starters dont seem to be in the game, sadly for you.
Theres also alot less grinding required. I was playing the game like usual and my pokemon overleveled and no longer obey my commands so i had to change to a team B. Thats me though, i was on every patch of grass trying to capture all new pokemon i see. It seems you dont need to grind at all on this one.

You liked Black/White, I hardly cared for it but I absolutely love X/Y, so going by that logic you should love X/Y even more!

For gens 3 and 4 I just didn't liked the settings, they were uninspiring to say the least. The starters were bland and it lack charm. Gens 1 and 2 are mostly nostalgia though. 

What I liked about gen 5 was the setting, team plasma was great, and N is a really awesome character. I dare say team plasma was the main reason I liked gen 5 more than the rest. Excluding some very stupid designs (like the ice cream and trash bag Pokemon) the designs were good, and the starters were cooler. I have the same kind of feeling with the gen 6 Pokemons, and the mega evolutions help with the nostalgia factor.

Alright, so it was the characters and story for you. I enjoyed that aswell on B/W. Unfortunely i cant comment on that enough yet. All i can say is that you got 3 friends and they sort of go along traveling alongside you. This is early story so i think its not a spoiler. You will be investigating the origins of mega evolution. I do believe i have already met the leader of team flare but im not sure. They seem to be about keeping beaty in the world forever (something like stopping time so beauty stays beautyful forever, that kind of thing). I wouldnt say its a premise as good as B/W but reviews say the story picks up after a slow start.

I think you should get it. Its definitly worth playing if you like pokemon games.

buy pokemon X/Y or i will send you a picture of me naked and very very sweaty.

i will swallow your cum if you buy the game...

Best presentation and multiplayer functionality in series history, interesting locales and new mons, polished gameplay, and the obsolescence of Pokemon Stadium. The only drawback so far seems to be the lackluster story, hardly something that most Pokefans put as priority #1.

The story is high on North Mythos in this game, I think you'll like Team Flare.

The dialogue in this game is way better than BW's

What did you dislike about gens 3 and 4 and what did you like about gen 5?
