ALV Tree (CL_SALV_TREE) is a grid which contains a hierarchy in the left column, plus additional columns which are common to all the lines. You cannot customize it.

|- root 1              AAAAAAAA BBBBBB CCCCCCCCCCCCC
|  |- child 1.1        AAAAAAAA BBBBBB CCCCCCCCCCCCC
|  |  |- child 1.1.1   AAAAAAAA BBBBBB CCCCCCCCCCCCC
|  |- child 1.2        AAAAAAAA BBBBBB CCCCCCCCCCCCC
|- root 2              AAAAAAAA BBBBBB CCCCCCCCCCCCC
|  |- child 2.1        AAAAAAAA BBBBBB CCCCCCCCCCCCC

ALV Hierarchical-Sequential List (CL_SALV_HIERSEQ_TABLE) can be used to display maximum two different structures, coming from two internal tables, one "leading" and one "subordinate", and you indicate which fields are used to join the 2 internal tables. You can't have 3 internal tables.

|- leading 1 AAAAAAAA BBBBBB CCCCCCCCCCCCC
|  |- subordinate 1.1  DDDDDDDD EEEEEEE FFFFFFFFF
|  |- subordinate 1.2  DDDDDDDD EEEEEEE FFFFFFFFF
|- leading 2 AAAAAAAA BBBBBB CCCCCCCCCCCCC
|  |- subordinate 2.1  DDDDDDDD EEEEEEE FFFFFFFFF
|  |- subordinate 2.2  DDDDDDDD EEEEEEE FFFFFFFFF

The List Tree control can be used to display fields as you want, but you don't benefit of ALV features:

|- root 1 AAAAAAAA BBBBBB CCCCCCCCCCCCC
|  |- leaf 1.1  DDDDDDDD EEEEEEE FFFFFFFFF
|  |  |- leaf 1.1.1  GGG HHHHHH IIIIIIIIIII JJJJJJJJJJJJ
|  |- leaf 1.2  KKKKKK LLLLLLLLLLL
|- root 2 MMMMMMM NNNNNNNNNN
|  |- leaf 2.1  OOOOOO PPPPPPPPPPPPPP
|  |- leaf 2.2  QQQQQQQQQ RRRRRR SSSSSSSSSSSSS
