Galaxy A7 vs S7?

I got my S7 during Prime Day and have been really enjoying it. The 120hz screen is nice, the sound is good, overall usability and power is awesome.

However, I saw today that the A7 is nearly £300 cheaper than the Prime Day price I paid for the S7, and I'm just not seeing the value here?

Is the A7 worse in any appreciable way to the S7? I use my tablet for light web browsing in bed, comics and manga via Tachiyomi, some light YouTube watching and to monitor my servers with Transdrone and LunaSea. Is the screen much worse on the A7, or would that be enough for my use case? Cheers!
