Some people prefer this photo software, also free, and very good;

I use a whole range of software for various things, but I'm not going to post it all here, it would be too much, and also wildly off topic.
Some of these things are a matter of personal preference, cost, and functions that one needs. You have to try them to see how you like them. The other major advantage of free software is that if you don't like it you can just discard it and try something else.
As with all this sort of stuff, there is a learning curve involved!
