Honestly, after watching these videos I think Zoma is quite damn good, but also has room to improve. I don't believe though that Zoma's neutral is as good as Taj's was. Compare the skill level of who Taj played vs Zoma. Granted, this is a few years back, but the Gods back then were still better than Zoma's competition.
The main take-away from all this is that Zoma probably has the most well-developed punish game. He punishes things even harder than Taj did. That's definitely something to take note, and it's what has inspired me to find new solutions to age old M2 tech problems.
Teleport shenanigans are also cool, but I would imagine that they are incredibly situational as they require such precise inputs and locations to perform them. Also, normal jump canceled teleport shenanigans are already quite good, and people don't use them appropriate IMO. I think the main and best use of the teleport edge canceling is to use it how Taj was working on it, as a means to get up from the ledge and to cancel on a platform for a possible punish.
