I think the issue here is that you're placing a lot of emphasis on Reinhard's blessings, while discrediting Reinhard himself, when Reinhard would be just as strong as he is now without them, yes he has cool stuff like deflecting projectiles, being a great cook, never mistaking salt for sugar etc but lots of the other stuff are fundament stuff everyone of a certain level has ie dodging stuff on instinct, being good at using weapons.
Reinhard has monstrous talent, to where even as just a baby his grandmother already sensed it, and things come easy to him them others, but I don't think that makes him any less "skilled".
Reid got as "skilled" as he is, that being the pinnacle of skill in verse in 3 months, meanwhile Cecilus who has the potential to reach Reid, hasn't gotten to that level despite spending his whole life trying to reach Reid. Both have the same talent, but Cecilus has had to work harder to reach that level, does that mean once Cecilus does get to that level, he is more skilled than Reid? As for Reinhard, he didn't just instantly get as strong as he is now, it took a little time.
Reinhard's capacity to instantly know the answer to stuff isn't due to his blessings, but a common thing among transcendents.
But any this is all semantics imo, whether you think he is talented or skilled, he is beyond people who can't be reached by the most veteran of soldiers and martial artist even in a lifetime, experience doesn't matter too much, and whether you think his feats of rain dodging are illogical, it still happened, so we should actually focus on the what each character can do here to win.
