You were downvoted but you are right. The podcast was released last week, but the game came with a day-1 patch to improve the performance on Switch which they would not have been able to try.

Obviously it will never compete with emulation on a PC, but it runs just fine on Switch. 99.9% of players are not going to think "wow, this would be much more enjoyable on a PC!" The gaming podcast crowd is not exactly representative.

Presumably they can run the pirated version on actual hardware as well (via custom firmware etc.), and therefore compare?

You can compare all the other releases, including Breath of the Wild, why should this release be any different? Especially when the emulator keeps improving and PC hardware keeps getting better
