I am going to try to be more neutral in this debate. In regards to Bio, I consider early game to be even, mid game Terran favored and late game Protoss favored. There is a reason why other Terrans and I make a blind bunker every TvP and TvZ and it is because early pressure from stalkers or lings is highly likely.
Terran can do the same of course, which is why I think it balances out. Terran’s chance to get ahead is in the mid game with stim and/or medivac timings. A small 5 minute window between the 5 min to 10 min mark roughly. 0-5 min is even and 10+ min Terran is on the backfoot unless he caused substantial mid game damage.
