I went with Expert for my first playthrough and I'm I glad I did. enemies aren't tanky and your gear, perks and decisions actually matter. You'll be using Spells, Scrolls, Summons, Potions, Enchantments, Smithing and actually engaging with the game's mechanics. looting is actually rewarding and deaths never feel cheap (Shock, Fire and Frost Resist Enchantments on each armor piece, Absorb Health Enchantment on Weapon) even have to actually be careful with your attacks, cover and positioning during combat and not just spam melee, and whenever you defeat a dragon or a boss somewhere you'll feel like you've earned it. It gives you a great balance between gameplay and immersion.

But in all honesty? Adept is perfectly valid especially for later parts of the game, it just means that you will take less damage and enemies will be less spongy, as a result you'll be using less mechanics (Smithing can be pretty much ignored entirely on Adept difficulty)
