With Pogacar going to the Vuleta, we'll find out once & for all whether the heat is something that bothers him. No hiding in Spain in August, it'll be brutal.
In fact in 2019 the Vuelta started 10 days later than it will this year (August 24th back then, August 14th this year), so this Tour of Spain will probably be the hottest GT he'll ever have raced in.
As for "who" is favorite, considering Primoz Roglic himself sort of owns the race & Spain in general (with Basque Country also) + he's the only one of the 3 favorites who won't have a full GT in his legs this season, I'd say it'll be too close to call between the two Slovenians. The presence of Bernal will add some extra excitement as well.
