NameCheap and WP Engine are two very different web hosts. WP Engine specializes in WordPress hosting, while Arvixe has many kinds of hosting plans to choose from. Since they are designed for separate kinds of hosting, they are a bit tricky to compare.
NameCheap has some of the cheapest hosting available. Their shared hosting can cost as low as $9.88/year, which comes out to about $0.82/month! Meanwhile, WP Engine’s cheapest plan, the Personal plan, costs a whopping $29.00/month. They have managed and custom WordPress hosting plans as well, which are far more expensive.
These hosts are so different, making it difficult to declare a clear winner. WP Engine easily outperforms NameCheap in plan features, uptime reliability, page-loading speeds, and technical support. However, WP Engine only offers WordPress, and they are very expensive when compared to other hosts. NameCheap, on the other hand, is one of the cheapest web hosts available, but their performance and plan features are nowhere near the level of WP Engine.
