From what I've seen with Zero-K (a Total Annihilation descendant) on Twitch, strong players play most of the time zoomed-out to see the whole map at once; some just disable the minimap entirely.

IANAPGM, but one can observe that TA and SC are indeed different RTS games in the sense that TA has a territory control focus (so perhaps a bit more strategic), while SC relies more on the micro/macro focus (workers, some skillshot abilities - which incidentally led to the birth of the MOBA genre).
