I mean it can be both, and it depends on what white wants. Keres attack (6. g4) will obviously make it more wild than the classical 6. Be2.
In general, if you are looking for a "solid" (I assume you mean more positional) opening, look past ALL sicilians. There are quiet lines in the sicilian, but only if white wants to choose them. If not, it's usually pretty much a blood bath, so if you are not comfortable with that, don't play it

Reason: edit: I wrote this assuming you mean 5.. e6, and not 5... a6 and then 6... e6
