LLL - which letters are premium?

Which letters are premium in LLL domains?

Can some help with order of preference of alphabets?

What do people say when they mean triple premium LLL ?

 

[Jeff]

It used to be:
A, B, C, D, E, F, G, H, I, L, M, N, O, P, R, S, T

The Chinese seem to prefer:
B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T. W, X, Y, Z

So u is not considered to be a premium letter for .in domain names?

I assume the reason behind why only selected letters are popular is due to the daily language used. For Chinese, those are how their Chinese characters spelled in Roman alphabets. But for other common letters, looks like there is a different pattern. @Jeff also mentioned that 'it used to be', so looks like it's different now.
