SSD SLC MLC and TLC which is good?

<1>
SLC = Single-level Cell, namely 1bit/cell, fast life, high price (about 3 times times more than MLC), about 100,000 times erase life
MLC = Multi-level Cell, that is, 2bit/cell, speed general life, price general, about 10,000 times---erase life
TLC = Trinary-level Cell, that is, 3bit/cell, also has flash manufacturers called 8LC, Slow life, low price, about 500 times erase life, there are no manufacturers can do 1000 times.
My suggestion is that the 64G selection of MLC because of the long life point of time also long Point
If the life of TLC above 128G is acceptable
