The reported "Maximum number of users" with Access can be misleading. Your actual database will only be accessed by one user - the web application itself, and each connection lasts only as long as it is opened then closed. Generally, that's fractions of a second. All the time that a user is just looking at a web page on your site, they are not "using" Access. I have had similar web sites running fine with Access where there are half a million database reads a month. However, if you are developing a site that expects "high stress and concurrency", you would be better using SQL Server. It just depends on what levels of traffic you expect.
