Which firmware is better for the Asus RT Ax53u: OpenWRT or factory firmware?
which one do you like the most, apples or bananas ?
Think of it as outdated, insecure and a security risk from the moment you purchased it.
By comparison, OpenWRT is the best way to enjoy your device -who’s absolutely decent HW wise- for many years to come with the best software security possible for such devices, as long as you apply the security patches once released —- for many years to come.
Timely patching with OpenWRT will always beat random one-two patches at most that you may be lucky to get using said factory firmware-regardless of the vendor.
What about bugs in third-party firmware?
They get fixed.
