Use whichever you feel most comfortable trading with.

With the default Standard profile, the Adaptive Kalman can indeed sit very close to EMA 21 on many charts. That is not something introduced by the MT version, and it is not a conversion mistake. The original Trading View version with its standard settings shows the same behavior as well. In other words, this is inherited from the original design, not something added later.
The important point is that the default profile is deliberately conservative. It gives a smooth and familiar baseline, which is why it can resemble a classic EMA on a lot of symbols and timeframes.
If you want to see the Kalman character more clearly, the settings that matter most are:
Measurement Noise and Model.
Useful starting points:
Standard 500 = conservative
Standard 310 = more responsive
Parkinson 824 = smoother swing profile
Parkinson 235 = more volatility-adaptive
Volume 235 = more activity-adaptive
Personally, I do not use it as “another EMA”.
I use it more as a dynamic baseline / state filter:
Bottom Line:
So the EMA21 similarity with defaults is real.
It is just not the whole story of the indicator.
