Before getting into benchmarks I would actually look which hardware capabilities a specific SoC supports first (eDP, HDMI or LVDS, USB ports, i2c, GPIO pins etc). Then I would check whether the manufacturer actually maintains mainline Linux kernel drivers or keeps an up-to-date downstream kernel. I look at their frequency for updates. For media systems having HW acceleration is crucial. Most ARM vendors do a crappy job of providing good open source drivers for this.
Similarly I go and check their Yocto BSPs. If I don't like their organization, that's going to affect my final decision. If it is a power-sensitive project, then the special modes and extra driver support for various sleeping modes come into play.
(Most of the time Intel just wins with those criteria because ARM ecosystem is a mess of proprietary blobs. However there are manufacturers like NXP and MediaTek who do release passable drivers and when power consumption is important they get selected or if the product is very price-sensitvie)
This website looks alright maybe for hobbyists for pure CPU loads with very well cooled systems. I don't find it very useful without the actual engineering details, adding those would massively benefit the website.
