Short version: I did enjoy Sw/Sh more than Let's go, mostly because of Gym/Raid battles and my character customization.
I did enjoy some elements of it. I loved that the battles with wild Pokemons were replaced by a catching minigame. I loved that you could play most of the game in co-op, even it being a super poor implementation. I loved how they integrated Pokemons following you, and you ridding them.
My problem with this remake is that, it has several short comings and some weird elements that just stop working. Battles become super uninteresting with the catch mechanic, so I opted to use co-op in all of them to steamroll everyone super fast. Because of that, iirc, I learned that in some places, like water, co-op doesn't work. For both catching and battling. Why? 🤷
Both games failed a lot in my opinion, in several areas, but mostly in game design, UX and in technical aspects.
But I would be lying if I say didn't love every single second I had while customizing my trainer, or doing my trainer card. It was also a blast going through gym battles, listening to the crowd, and seeing the gym leaders personalities. I just wished they had voice. It would be so much better. But since Pokemon screws new things they add, I'm scared of what might come of this. My first time going to a wild/open area was also amazing. It had severe issues, like: severe fps drop, poor weather implementation, assets quality, camera work; but the most disappointing thing about the wild area is leaving it. Even with several issues, it was so much better than the corridors the game makes you go through.
