The Portico Method is a 3x3 speedsolving method created by Matt DiPalma before 2017. It is derived from the ZZ Method, and the two share very much in common. The main difference is that ZZ's EOLine is replaced by EODB (the DF edge is omitted). Then, for the duration of the solve, the user is free to use F2 moves and the M'(U)M moves to solve F2L (which increases blockbuilding efficiency). The third step is COLL (42 algs). The final step is EP5 (15 algs), which solves all 4 LL edges and DF.

ZZ has 11 fewer algs

Portico features easier inspection and superior blockbuilding to normal ZZCOLL/EPLL. Omission of the DF edges also accommodates more ergonomic CxLL algorithms. This of course, comes at the expense of 11 additional ExLL algs. However, many of these algs are short (M' U2 M) or memorable (M' Hperm M). See the references for the algorithm list.
