Alot of people have made that silly arguement before that zerg can replinish entire armies all at once, failing to realize that means you have a ton of resources piled up, which is never good. And only bad terrans turtle up and stay, the rest can keep you choked up with scans/scouting and just dropship/harass if you try to move out, terran are really good at that with MM drops/hellion/rapers. Terran turtling also usually means expanding and just adding more bunker/tank/tower since they can defend bases easier. Bonus on creep is 30% movement, but off of creep units like hydra are much slower. Its most commonly illustrated that if a terran and zerg player are of equal skill, the terran will win, unless they screw up real bad.
That's interesting view. Kinda reminds me of the early days of Pro starcraft, where it was all protoss vs zerg, and terrans were thought to be a terrible race. Then came Boxer, Nada, Iloveoov, and others who showed how to play the race effectively.
Here is a nice TvZ set that shows the races well. TLO (The Little One) usually plays random but is a fantastic terran player. Its a close and entertaining matchup, all five games. Take from it what you will
