do these expressions have the same meaning? 1. As well as shoulder bags, I'm also a big fan of backpacks 2. In addition to shoulder bags, ... 3. Besides shoulder bags, .... 4. Apart from shoulder bags, .... the second half the above 4 sentences is the same, but I am confused if these 4 expressions are all exchangeable. I want to say, I love both backpacks and shoulder bags. Thank you very much!
