Love the entire series. The ones I've played anyway. Haven't touched the DS ones.
LttP was the first game I ever beat. I've played through it 17 times, at least and remember how to get everything. Well, that's a lie. I NEVER managed to beat the *** digging game for the last Piece of Heart. Easily spent 4-5 hours in any play through attempting it. Makes me rage. :<
OoT has the best memories for me. My grandpa and I worked through it together the first time. Then I proceeded to beat it 15+ times after that. Now that I think about it though, I've never done a 100% run of it. I should get on that.
Majora's Mask is my favorite. I like how much you have to interact with everyone in that world. I liked how morbid it was. How dark it was. I also loved the various link forms. I did a 100% run for that. Fierce Deities Mask is amazing. Games fairly short if you don't do any of the side quests though.
Love Windwaker. Unfortunately, I've never managed to beat it. Either memory card being stolen, game being erased by a careless brother, or said brother throwing a tantrum and snapping the disk in half. I raged hard.
I enjoyed Twilight Princess, but it wasn't as... awe inspiring I guess. Solid and fun same, but it didn't attract me like the others did. :/
Link's Awakening was just sad. Fun... but sad. ;_;
Never finished Seasons/Ages. I've got the cartridges around here somewhere... I'll probably just emulate them though, since my GBC/A are long gone.
