BW was a fine reading all through, but I'd say I like more the games' story in this case.
Personally, I think a good BW alternative to
Adventures is Ky-nim's comic
Myths of Unova. While most nuzlocke's comics I've seen can be kind of cringy, this one has a strong consistent plot, does a good job at expanding the lore of the Unova region, & know how to handle an OP character without making them look like a Mary Sue
As for
Adventures as a whole, the Kanto & Johto arcs are great while everything else has either been meh or a hot mess. There are still some sagas I liked such as BW & RS (plus SWSH is doing good so far), but they're only really memorable for a few scenes or characters while most of the time the storylines are just ok. Later arcs such as BW2, SM, & XY have a habit of starting off strong but then go completely off the rails in terms of story and characters, that by the time they end they feel like rushed dumpster fires.
If anything, the two things I consistently love about
Adventures are the personalities it gives the protagonists and how the Kanto gym leaders were (at least to me) written better here than they were in the anime with the only exceptions being Brock & maybe Misty.
While I hate to sound like a Genwunner, I honestly think the Kanto arc is the best story in
Adventures. It has a strong, consistent story, features memorable characters through the protagonists and the gym leaders, make Team Rocket feel like an actual threat while sticking to the motif of genetic engineering, & does a great way to visually bring the world of Red & Blue to life through minor details like the buildings and the environments. It honestly feels more like an adaptation of Red & Blue than the anime or the side series, while also feeling like classic films like
ET or
The Goonies.
