It is very hard to objectively judge laws specifically and political systems in general. The only way to do so is to look at their outcome, but with the large amount of variables, and the time it takes to draw conclusions, objective facts about them are hard to make.

The world in general has concluded that planned economies (communism) is strongly inferior to market economies, but during the early days of communism it was not so obvious. Even in modern times there are people that argue communism was implemented prematurely and would be able to thrive during "end-stage capitalism". You also have plenty of people who while disagreeing with a complete communist revolution would still support nationalisation of key companies or even the more radical "workers being in control of the means of production".

Free speech is even less clear. With america winning the cold war there was a recognition of the american way including the strong support of freedom of speech being the superior system. However lately, especially after 2016 the west seems to have lost confidence in the absolute freedom of speech. Challenging the supremacy of the freedom of speech is the idea that citizens are not capable of judging speech on it's own merit and "misinformation" "speech glorifying violence" etc should be banned. It's not really a clear cut issue, you can for example argue that limiting free speech leads to a more harmonious society (the position taken by China, and also lately the reason given by New Zealand for their decision to ban the Christchurch manifesto)
