One might think that based on the model numbers MX4200 and MX5300, the Velop MX4200 might be a more inferior model. But it is actually not true, and in the real world, you might not notice the difference.
Linksys Velop MX5300 Wi-Fi 6 was launched in Singapore on the 20th February 2020 for S$569. At launch, it was exclusive to Challenger and Hachi.tech. Other retailers started selling from 20th March 2020 onwards.
