It is important to remember that when you sign up with a web hosting company, you are not just purchasing a set of technologies. You are also entering into a business relationship. There are many non-tech reasons why you might choose one host over another. You need to be able to trust your hosting company. This is where customer reviews can be very useful.

If industry-leading uptime and rapid-scalability are your two biggest concerns, cloud hosting might be just what you're looking for. Cloud hosting will get you access to a cluster of servers from which you can quickly provision resources when you need them. Along with having enough separation from unruly neighbors, your application should be kept safe. VPS and Cloud services are sometimes combined into a hybrid service called Cloud VPS or Scalable VPS.
A few companies have offered low-cost, below-cost or even free domain registration with a variety of models adopted to recoup the costs to the provider. These usually require that domains be hosted on their website within a framework or portal that includes advertising wrapped around the domain holder's content, revenue from which allows the provider to recoup the costs. Domain registrations were free of charge when the DNS was new. A domain holder may provide infinite number of subdomains in their domain. For example, the owner of example.org could provide subdomains such as foo.example.org and foo.bar.example.org to interested parties.
The company doesn't list a virtual private server offering, but they bill their Elastic Sites service as a VPS alternative, offering the ease of use of a simple shared hosting plan and the performance and scalability of a VPS. GlowHost also offers a number of different cloud hosting plans, with special attention to providing enterprise-grade services.
I wanted to point out that you do not mention critical issues. One is that some of the Top 5 Hosting Services do not offer an e-mail account. Others charge $14.00 a year to transfer your a Domain Name and host it with them or else the domain owner does not get the hosting for free. The list of unpleasant conditions that render those top 5 Hosting Services substantially less appetizing than you painted the picture, and that list goes on and on.
The answer is simple – despite having many different names, all of these companies belong to the same German AttractSoft group. That may not necessarily mean something evil – it could be that each service is just meant to cater to a different market and/or audience. For example, Awardspace is more popular in the US and India, while Netfirms is a well-known name in Canada.
Simple websites are best for low to medium trafficked sites with multiple authors and more frequent content changes, such as marketing websites, content websites or blogs. They provide a simple starting point for website which might grow in the future. While typically low cost, these sites require IT administration of the web server and are not built to be highly available or scalable beyond a few servers.
Second-level (or lower-level, depending on the established parent hierarchy) domain names are often created based on the name of a company (e.g., bbc.co.uk), product or service (e.g. hotmail.com). Below these levels, the next domain name component has been used to designate a particular host server. Therefore, ftp.example.com might be an FTP server, www.example.com would be a World Wide Web server, and mail.example.com could be an email server, each intended to perform only the implied function. Modern technology allows multiple physical servers with either different (cf. load balancing) or even identical addresses (cf. anycast) to serve a single hostname or domain name, or multiple domain names to be served by a single computer. The latter is very popular in Web hosting service centers, where service providers host the websites of many organizations on just a few servers.
Once you decide you price range, you need to consider how long you'll need web hosting. If it's a short-term project—say, less than a month or two—you can typically receive a refund should you cancel your hosting within 60 days. Some companies offer 30-day money-back guarantees, others offer 90-day money-back guarantees. Once again, it's beneficial to do your homework.
Registries and registrars usually charge an annual fee for the service of delegating a domain name to a user and providing a default set of name servers. Often, this transaction is termed a sale or lease of the domain name, and the registrant may sometimes be called an "owner", but no such legal relationship is actually associated with the transaction, only the exclusive right to use the domain name. More correctly, authorized users are known as "registrants" or as "domain holders".

On the plus side, SiteGround offers free automatic daily backups, access to the Cloudflare CDN, high-performance SSDs for all plans, unlimited email accounts, and integration of the free LetsEncrypt SSL certificate into sites. The company does limit bandwidth and storage, but even those who claim to offer so-called unlimited bandwidth and storage really have some limits in their terms of service.
