Yes, prestashop is faster than Woocommerce. I manage two e-commerce with both. But while with Woocommerce all I needed extra was a $15/lifetime stock synchronization plugin, with prestashop I would need $100/month of plugins to have feature parity. So I keep prestashop basic as an simpler store under a different domain that doesn’t need stock synchronization or mass import or blog.
Odoo, I loved it at first sight when I tried the 30 day trial 5 years ago. So much snappier than Woocommerce, and with so many features. Its main problem was price and complexity. Official hosted version required a subscription for every single feature. Invoices? That’s $19/month. List of clients? Another $19/month. Blog? Add $19/month. For the tiniest extra feature, needed a subscription. In the end the full package was completely unaffordable and the bare minimum was unusable. The free self hosted version is the most complex install that I had to do in my life. I installed a third party plugin and I broke it beyond recovery. Because it’s in python it requires a dedicated server and not a normal hosting. Unless you’re a Linux guru you have to pay for their hosting service. Luckily recently they realized that their pricing was unaffordable for everyone except huge corporations, so now the full package is around $20 per month.
