The difficulty modes do work, it's just the stats that are buggy, if you pick Challenge Mode you'll be met with trainers using stronger Pokémon, having improved AI, held items and EVs (the buggy stats is just the base stats, in Normal Mode they didn't use EVs)
Low quality sprites is subjective. Most people actually enjoy them.
Actually it is subjective. I could name multiple facilities in later games that are worse, there's the XY Battle Maison, which, despite having more features compared to other Battle Tower clones, it was painfully easy, Battle Agency in USUM was boring, it was kinda similar to the Battle Factory but it was straight up worse. SWSH Battle Tower which was somehow even easier.
It's still praised as the best story in Pokémon. Even actual writers outside the Pokémon fanbase agree. While the story isn't the best, it's still better than any other game in the series, though imo SM had a better one.
