I love the aesthetic of Fantasy, but the gameplay is boring as shit. You can watch one game of Fantasy and you've essentially seen every game of Fantasy played this edition. You bring an infantry Horde, put a level 4 and a Battle Standard in it, then grind into your opponent's infantry horde with level 4 and BSB. I tried to escape from the absolute stagnation by playing a more unusual army, Ogre Kingdoms, but they're exactly the same as everyone else. Giant blocks of cheap infantry, Level 4 spellcaster, BSB, war machines. All those awesome-looking Fantasy models, the monsters and stuff? Yeah, you're never going to use it, because it will get hit by a cannon and die horribly, and can't fight half as well as a block of infantry. Cavalry, skirmishers, monsters - they all make Fantasy look varied to an outsider, but they're just a ruse of models to hide the very simple game of 'let's sit here with 50 guys on each side and roll dice for four hours'.
Lore of Death is hands down the best lore (not counting Shadow, which broke the meter when I tried to gauge how stupidly strong it is). Not because it's all that great, but because you can snipe the Battle Standard. Break the Battle Standard, and the game becomes about a thousand million times more fun and interesting because there's a whole new section of rules that deal with people leaving the twenty-four-hour-slugfest of combat. Oh, and it has one of the scary wipe spells, which saves you wearing away the bones in your wrist because you're still rolling for the combat that started when 8th edition came out.
