Your answer will depend on the type of the language you are using, and the type of the program you are writing. Some will be better than others in some situations and others will worse that others in other situations. The best way really, is to use them in different programs and/or languages and learn for yourself which is the best for you. Everyone’s answer have their up’s and down’s, but it is up to you to decide. I hope this helps you!
