Which router for an apartment from TP-LINK to choose?

Question

Computer networks

Subject. I went to the TP-LINK official site, and there the C60, C50, A5, A7, A9, C5, C7, A6, C6 are almost the same. I tried to compare, but their information is not structured in the best way.

Now I took a C5 model from a friend to indulge in, everything seems to be running well. IPv6 started 2 clicks. WI-FI 2.4 and 5 also works properly.
Isn't the C5 old compared to the C6 and C7?

At home from devices:
- 4 phones (2 support 5 Hz Wi-Fi)
- AppleTV
- laptop
- PC via cable

Something very complicated, help.
