The Razer design is nice, but as someone with a blade who's battery bulged within only a year of moderate use because cooling was clearly an after-thought to looking good, I wouldnt be quick to trust it.
Then again, maybe they've improved since then. Mine was a 2019 model after all.
Something to be wary of: Razer has a bad reliability reputation, in conjunction with bad customer support. The glowing remarks usually come from people who Razer has a vested interest in pleasing.
