Although I've read these two posts:
I would like to ask again specifically about Texmaker and TeXstudio, because they are quite well ranked in the "Big list", and one of them was born as a fork of the other one.
What are the main differences between them? What are the advantages and drawbacks of each of them with respect to the other one?
If you changed to one of them after using the other one, what made you change your mind?
I think these questions are specific and different enough to deserve their own post…
As it can be deduced from my question, I am mainly interested in knowing the experience of people that have used (or at least evaluated) both editors. I know I can read the "features" page in their respective websites, but that's not what I am looking for.
This quote explains the main approach of forking Texmaker in the first place. The last sentence indicates that they became two fully independent programs. Only the GUI seems similar but the rest is hard to compare.
On performance: The time consumption will be difficult to measure, but you can do it your self by downloading and testing both. They are both free. The main aspect will be the look and feel while working and depends mainly on the layer 8. I like TeXstudio more, but this is completely opinion based.
You can compare the download size and the space occupied on the system and post your results here. As TeXstudio comes with more features (I hear), I guess it will be bigger.
In order to decide which one sounds best for you, you will have to read the Texmaker feature list, the TeXstudio feature list, the comparison list on Wikipedia, and the answers and comments in our editors big list. Or you come to chat and discuss single topics with other users.
