Okay hereby you have some 'research'.
'If you know how to proper configure wordpress, woocommerce and plus marketplace, on the woocommerce is endless possibilities. you are talking about over 25% of ecommerce systems of internet. from your words, I can see it clearly that you did deeply dig the all systems. talking is easy, but it has to be logical and the right judgement.'
Yes I have properly configured it for many clients, it's just a complete disaster, nothing is placed in a logical position and it still remains a blog cms. A blog CMS is built for blogging, not for selling goods. Surely it can power just 25% of the entire community, but the big companies (with over 10 million in revenue) using wordpress can be counted on just one hand, which should speak for itself.
'from your words also can be understand as well, you didn't deeply did research about magento. it doesn't cost you 100k, who says that? with the community edition, and plus modules, you can do every thing. of course if you want everything included ready to use system, it will cost you more for the service. it's even more costs you on the cs-cart, or maybe not big difference. but in the end, it will be ready to use website and service. that's reason why many people don't like service, and prefers buy license and module.'
How do you even compare Community edition with Enterprise? For starters, community edition isn't even PCI compliant. Secondly, the license does cost you 100k. The pricing scheme of magento is as follows:
Magento 2 Enterprise Edition (EE)
Magento 2 Enterprise Cloud Edition (ECE)
Sales EE ECE
$0 - $1 million $22,000.00 $40,000.00
$1 - $5 million $32,000.00 $55,000.00
$5 - $10 million $49,000.00 $80,000.00
$10 - $25 million $75,000.00 $120,000.00
$25 - $50 million $125,000.00 $190,000.00
So yes, it costs you 100k. Surely you can install modules and everything but that doesnt give you a 24 / 7 Gold SLA and many more features.
and, you are completely mistaken on the hacks. what you said "SQL injection bugs, CSRF bugs", those are old hacks of internet. it was very popular in years 2002~2004. what you said is not something new or shocking things for majority users. as well you said magento is open source, then answer this question; is the cs-cart closed source? it's nothing to do with it's open source and because of open source, people use magento and cs-cart. logic is basic, the TRUST. if no TRUST, no body use it even if you give it for free. and, you are talking about security too much fast, without doing your own research....
So Magento is secure? No it is not, check out the recent exploits overhere:
https://magento.com/security/author/Magento%20Security%20Team
I quote from one of their fixes (Nov 2017) "Magento Commerce and Open Source 2.2.1, 2.1.10 and 2.0.17 contain multiple security enhancements that help close Cross-Site Scripting (XSS), Local File Inclusion (LFI), authenticated Admin user remote code execution (RCE) and Arbitrary File Delete vulnerabilities."
Also, I don't have to do my research because how often I have to hotfix these bugs is insane. This takes up at least 30 hours a month.
cs-cart is really slow. it took me 25 seconds to open the page when new install. then continuous optimization, currently less then 1 seconds. that's just 1 second and I do think it's slow. here I don't compare with slow website like you said 8 second and foolish myself and think my website is fast. but it's slow! you maybe making a money on cs-cart and like it, but what you said is not right thing. currently some ecommerce systems page opens even just 50ms or less. seems like you are trying to say something you didn't research well.
With a new install? That just means you configured the server poorly. We achieve (without any caching whatsoever) page loading times of under a second without a problem. With our full page caching this can be brought down to just 400 m/s (with a TTFB of just 20 m/s). Also, CS-Cart has programmed a solution for this as well. The page loading time can also be 400m/s by using their free Varnish implementation.
like I said before, it's included many modules and plus well organized on core, menu, mobile version. but I think this one can be much more improved. but cs-cart company doesn't give you ready improved system for the expensive price, you have to invest more money and time, and money. this is making one kind of problems for cs-cart's market share. for that reason, on this forums we have too small community.
Expensive? CS-Cart is basically the best bank-for-your-buck you can get at the moment. I really can't see your point here. CS-Cart's cost compared to it's features is extaordinary.
there are many reasons why cs-cart is not known in France. I completely agree with FLOW on above comment. as well, there are many many reason could be find if you do research.
Surely there are many reasons, there are just fewer than Magento. Yes, surely a french website would be great but why a french website when everyone around the world speaks English? Futhermore, you do not need any add-ons whatsoever to make it work in the EU. I don't get where you got this information from. I'd be great if you could tell me.
