These are basically all the same reasons that I prefer White 2 as well. The only thing that I was a little disappointed in was that Black 2 had a fully developed Route 4, while White 2's looked like an abandoned archaeology site.White 2 for me, though I wish some of the exclusive Pokemon could have been swapped. :c
Other than that, I love how homely it is compared to the differences in Black 2, with its old stone buildings in Opelucid, and giant towering trees in White Forest. <333
