For me, I'd actually have to give the level design crown to gen 1. All the caves and forests were wonderfully constructed mazes, and a few of the gym puzzles were interesting as well.
The worst level design is hands down gen 5, though I'm not even sure you could say gen 5 even had level design at all. Everything was just a straight path. The game pretty much never let me figure out anything on my own, and just pulled me along with the story. --- Any sig ideas?
I liked Generation II. The whole split after Ecruteak thing, where you can choose to go left or right, really threw me off and I had a good bit of fun just exploring every nook and cranny of the routes east of Ecruteak and north of Mahogany before I realized I was supposed to go west from Ecruteak and then head to Olivine. --- By Right of Blood... by Right of the Seven who wove it, I would see through the veil of time!

My favorite design has to go to the psychic gym in this gen, loved that sphere mechanic. --- | 3DS Friend Code 0430-8284-1167 | Gamertag: UltimaWraith Vs. Recorder Videos: 73PG-WWWW-WWWX-UQD3 & UUNG-WWWW-WWW2-K47K
Gen 5 since it blocked off cities/content in both BW1 and BW2 until you beat the game or completed after-game events. . . Which by then it's like "what the frick's the point?" It was also just a straight line too, which sucked.
In Gen 6 they fixed that up by a tiny bit with somewhat straight forward caves that had extra areas to them. Also having Terminus be a "side thing" was pretty nice. Though the straight forward path kind of zigzagged twice instead of doing a full circle, so I liked that at least. --- I juss dun understayand.
Best - Gen 3. Had awesome secret areas and fun places to explore like the volcano and dive areas. People just hated it because of the vast amounts of water, but I loved it. There was even a city hidden through an underwater cave! --- HOLDING ONTO HIS DONG. HOLDING ONTO HIS DONG AND placing it on Hibbert's chin.
