あちこち is more common and casual, meaning 'all over the place' or 'here and there', while そこここ is slightly more literary and emphasizes scattered locations.
ところどころ also means 'in places' or 'here and there', but is more neutral and widely used; そこここ can sound a bit more poetic or descriptive.
Reduplication of そこ (there), with the second element voiced for euphony. The kanji 其処此処 are ateji based on meaning.
