If you hire a decent web developer then they will tell you.
Hint: it doesn't matter how fast the view tech is if your server crashes all the time, it takes you three years to make a change, and users can hack your site in 2 seconds. All of those things are way more important.
Plus, if it's an e-commerce site then you have to take into consideration taxes, VAT, etc... it's extremely complicated. Better to let someone else handle the money (like Steam) and go with a prebuilt solution for everything else.
Or hire an experienced web developer and pay them well. And if he's any good, he will tell you exactly what I just did.
