After trying lots of texture packs: Doku's, Painterly, etc... I've found my favorite to be Zombuster's, as it's as close to the original as possible, while being higher res. (If I want a different feel for the game, I go with the Zelda pack) The only problem is that the Zombuster pack I've found is still a WIP. I managed to modify some blocks to fix other blocks (Gold/iron/redstone/diamond ore fixed with coal ore, ice fixed with glass, snow-covered dirt fixed with grass-covered dirt), clay fixed with sand, burning furnace fixed with non-burning furnace).
And Zombuster's WIP texture pack (With the ore/clay/etc changes), as long as Zombuster doesn't mind.
