ZZ44 method is a 4x4x4 speedsolving method proposed by Quoc Hung meant to suit users of the ZZ method. It can also be applied to bigger cubes.
It similiar to Hoya but with EOpairing.
The step
 F2C: Two opposite centers (not U/D ones).
 D and B centers.
 Pseudo cross edge
 Place any 2 oriented edges on the BR and BL spots
 Last 2 centers.
 Edge pairing
 Finish by ZZ (EO+Parity OLL, ZZ F2L, COLL, EPLL+Parity PLL.)
The Pseudo Cross
 Pseudo Cross for EOLINE solver :
1 line edge + Any good edge at DL(or DR) cross positon.
 Pseudo Cross for EOArrow solver:
1 Line Edge + DL(Or DR) cross edge.
Last Layer
For the last layer, you can use the same COLL algs as on 3x3, as you don't need to worry about orientation parity due to it being solved already.
After COLL, you have EPLL+parity. There are the 4 normal EPLL cases (Hperm, Uaperm, Ubperm, Zperm), plus the additional opposite swap, adjacent swap, Oa, Ob and W permutations.

Do the correct algorithm out of the 9, and you're done!
Pros
 Gives a ZZ finish for a low movecount than Hoya,similar movecount to Yau, with all of the advantages Hoya has.
 Easy look ahead
 Less cube rotations
 The most used moves are Rw, Lw, L, R, U. Very few F, B moves. Resulting higher TPS.
 Better ways to deal with parity. The number of algs used in a solve with double parity is one less than with standard Yau with double parity, and PLL parity recognition is easier due to corners being solved.
 Suited for ZZ solver
Cons
 L2C can be a little hard.
