TP-Link Archer A6 v3.0

Hello Everyone,
I have bought TP-LINK Archer A6 V3.0, I am a normal user , I use 5 Smart Phone, 1 PC, 2 Android Box, Normal Download , OTT, Live Tv etc.
I don't want to reboot the device everyday, The device should last few years if I get lucky.

Now the question to all expert, which would be the best for my requirement including stability , performance , no heating issue / hang /lag etc between Archer C6 v2.0(Qualcomm Atheros) or Archer A6 v3.0(Mediatek)

Till now I have the opportunity to change the router.
Please suggest / need help / need recommendation.

Thanks in advance.
