After trying both the Oculus Rift and the Lenovo Explorer virtual reality headsets, I believe I can give an accurate comparison between the two. Both of these headsets have a 110° field of view, 90 Hz refresh rate, and 360 tracking capabilities. The first difference lies in the resolution; while both are high-resolution displays, the Oculus Rift offers 1080 × 1200 px while the Lenovo Explorer offers 2880 × 1440 px. This is definitely a pro for the Lenovo Explorer since it gives you more detail and sharper images.

In terms of power requirements, this is where there's a big difference between them. The minimum CPU required for running the Oculus Rift is Intel i3-6100 or AMD Ryzen 3 1200/FX4350 or greater. Meanwhile, for the Lenovo Explorer it requires an Intel Mobile Core i5 Dual-Core with Hyperthreading instead which means that you need more powerful hardware to run this headset than what's needed for its competitor from Oculus. However, despite requiring higher specs on paper, some users may find that their computer runs better with a lower CPU than what's necessary for either headset — so this could be seen as a plus point for flexibility depending on your existing setup.

The graphics card requirement also has a wide range of options depending on which headset you're looking at; with Oculus Rift needing Nvidia GTX 1050Ti or AMD Radeon RX 470 or greater while Lenovo Explorer needs Intel HD Graphics 620 (GT2). In my opinion however, none of these graphics cards require too much power to get good performance from either headset — but again if you have existing hardware then it will make choosing one over another easier since you don't need to upgrade your graphics card to run it properly.

When it comes down to personal preference when using either headset, I would say that I preferred using the Oculus Rift over its competitor from Lenovo due to its lower power requirements and more comfortable design overall — which makes playing games in VR much more enjoyable experience overall. The only downside I found was its slightly less sharp image quality compared to the Lenovo device; but considering how much easier it was on my wallet (both in terms of hardware requirements and price) I felt like this was worth compromising on slightly given that most games still look great even at 1080 x 1200 resolution anyway!
