I play both sides, and at the moment I’m concentrating on my last two Reps to unlock Kul Tirans and DI Dwarves.
From my perspective, this expansion, things are easier for Alliance.
The city is easier to navigate, and the whole city is a resting zone. The War Table and ship, as well as the Campaign quest holders and Warfront table are in close proximity to everything else. As is the armour Scrapper.
The quests are easier and more convenient, the rewards are much better, and most treasure chests on Kul Tiras contain the Polished Pet Charms. Which is strange!
Even Nazjatar starting Quest; Jaina floats the Alliance Character gently to the quest giver, while Oculeth bubbles the Horde player, then allows them to fall into the water and swim. No hassle at all, but I feel that Blizz has made the Alliance experience softer, more convenient, as though they feel the Horde can ‘take it’.
I think that is the crux of my Alliance experience; it is gentle, precious, while the Horde experience is more robust.
Maybe the player-base has created this reality, I don’t know, but it seems quite valid to me.
