Should I get 2E or 4E?

Hey there, I'm in a bit of a dilemma here. I'm considering investing in either 2E or 4E, but I'm not quite sure which one to go for. Could you please help me understand the key differences between the two? What factors should I consider before making a decision? Are there any risks associated with either option? And ultimately, which one do you think would be the better choice for me? Thanks in advance for your help!
