Flask make_response or app.response_class for return json response from flask view

Question

I have readed return-json-response-from-flask-view and flask-response-vs-flask-make-response. And I still have the question:
Can I do json response with make_response or have to use app.response_class? Because they differ !!
But in real code make_response works as well.
Look this code

import json

from flask import Flask, make_response
app = Flask(__name__)

data = {'easy_key': 'any_value'}

with app.app_context():
    resp_maked = make_response(json.dumps(data))
    resp_maked.headers['Content-Type'] = 'application/json'  

    resp_classed = app.response_class(
        response=json.dumps(data),
        status=200,
        mimetype='application/json'
        )

    print(resp_maked == resp_classed)

It gives False. Btw

In [5]: resp_maked.headers
Out[5]: Headers([('Content-Type', 'application/json'), ('Content-Length', '25')])

In [6]: resp_classed.headers
Out[6]: Headers([('Content-Type', 'application/json'), ('Content-Length', '25')])

In [7]: resp_maked.json == resp_classed.json
Out[7]: True

In [8]: resp_maked.json
Out[8]: {'easy_key': 'any_value'}

Another question is - what is better to use if I want to reproduce jsonify by myself?
