Both are ACCURATE as I use both ONLY the TEA LEAF cards are limited to certain spreads really and are a bit vague until you work out how it works in with your week, for example.
Lenormand can answer SPECIFIC questions and to the point depending on the method you use.
TEA LEAF: 200 cards...give or take. LENORMAND: 36 to 38 cards.
Example of my tea leaf reading from last Sunday: WEEPING WILLOW = Family Loss
Elderly neighbor died either Sunday or Monday afternoon and sadly not family to me, but WE were family to him that live here, so I think that is what the card was saying.
And I had this SAME card in the 2nd week of January and someone known to my family...well, her son killed another person known to our whole hometown in NZ. Drunk fight, so not intentional.
So, the TEA LEAF are quite on to it, but just not in a very direct way.
