I know both guys and actually use Strider (am more than happy with my site and get lots of work from it). I have seen websites from Epic flowers too and Brandon is doing a lot of work with mcommerce I think. They are very nice.
I think with any site provider you have to have input yourself on how you want your site to look so that it is different. You also have to put lots of work in adding pictures and information and showing it as a second store independant yet streamlined with your brand.
I would be happy to recommend Strider and always have. If you have any questions feel free to pm me.
