It’s all about the product – it’s easier to market quality software then a web based platform.
I’d recommend that you test both of the product, talk to someone who has experience and then decide.
Because if you’re working on a rev share model and the customer is not satisfied with the software then you end up making $100 when you could have made $10,000
On a personal note with the latest events in the industry I’d strongly recommend considering forex as an alternative.
