Here is what the differences between each solution and how I suggest you pick one.
First of all, for many of you, whatever you decide, you will be able to change your mind later. What you know and what you want to do today might not lead you to the same conclusion and decision you will take a year or two from now.
Second, these solutions evolve all the time. And new players might come up with something new next year or the year after...
Third, do not base your decision on what you are good at... Like going with a WordPress solution because you already master that product or that you are very good with websites, servers, etc.
Why? Because you are not considering the Sales Funnel path because of something you are good at but most probably because you want to get more sales results. Right?
This is why
