To be fair, there isn't one more tactical than the other, both TpT and Rtwp have overall the same features. Its a matter of feeling. Some people appreciate the versatility and the flexibility of Rtwp, and its more cinematic approach , while other like the slower, more mathematic system of TpT, that allow you to consider quietly each actions and doesn't burden the player with the decision making of ''when to pause'', nor bother you with the micromanagement than Rtwp often demands.
The attack,spell, feature, zone, bonus actions, and whatever combat thing you can do are possible in both mode. Some people like it one way, some people like it the other way, and some people like both. And that's that.
