Monitor Recommendation (25 characters)

For context, I have two monitors
Koorui G2411P 200hz (main monitor) bought 2nd hand this Feb (2-3months old ata sa owner)
Koorui 24E3 165/144hz (2nd monitor) sumuko, I posted last time about it having horizontal lines, now mas lumalala and may blackspot na(see image below)

Tinignan ko yung monitor Guide, nakita ko yung Titan Army 260hz, isa sya sa pinag pipilian ko or another Koorui G2411P, para same panel sana. Should stick with koorui or buy Titan Army? Budget ko lang 6k sana kaya medyo limited. Thanks!
