Personally I generally go for something in between, so here's what I've got and works well attacking and defensively.
Attack: fluid, attacking, play offside, higher tempo, more direct passing, run at defense, play out of defense(ignore if you have Shawcross esque centre backs), more disciplined, adventurous formation(4-2-3-1, 3-4-1-2, 3-4-3, 4-3-3, 4-4-2 diamond)
Defense: fluid, counter/attacking/defensive, cautious formations(4-2-2-2, 4-5-1, 4-4-1-1, 4-1-4-1, 3-5-2, 4-4-2) play offside, higher tempo, more direct passing, run at defense, drop deeper, play narrower(or use a narrow formation), more disciplined, clear ball to flanks(ignore if narrow formation), strikers man mark midfielders
