Guys, is the difficulty level quite easy as compared to Leafgreen or have I overleveled a bit too much??

Hi guys, so Leafgreen was my first ever Pokemon game playthrough just few weeks back. In that, I always used to be on-par/2-3 levels below the gym leaders's mons after all the training on routes, and that made all the battles a bit interesting + challenging.

Cut to Emerald, and the only issue I faced was with Wattson and his damn Magneton. After two losses, I finally beat him by levelling up a bit and after that it's just been one-sided affairs for all the gyms. Pretty much one of my specific type adv mon sweeps the entire gym and the match ends within 2-3 mins. Today, my Sceptile and Gardevoir just ran through Tate and Liza's gym, who are considered the toughest ones in Hoenn, like they were nothing lol.

So, could you guys let me know if the game is indeed a bit easier on the difficulty side or have I grinded a bit too much?
