Share ko lang personal experience ko.
Gamit namin dati is yung PLDT ONU FIBR oem modem/router lang. Works fine for simple use pero nung dumami devices sa bahay napansin ko madalas mawalan ng net and need i-restart yung modem. Upon checking, napansin ko na masyadong mataas yung cpu usage kapag madaming naka connect. It seems low-end cpu lang gamit ng stock cpu modem.
I opted for TP-link na may MIMO and 5Ghz wifi. Got only very slightly faster speeds pero ang malaking improvement ay sa stability. Also maganda yung control panel ni TP-link and plan ko din mag upgrade to mesh wifi na TP-link din. Take note na di mo realistically mapapalitan yung modem ng PLDT. In my case, modem ko is PLDT pero lahat ng router tasks is handled by the TP-link. Eto yung nag solve ng high cpu usage ng stock modem ko.
In short, unless may use case ka na di kaya ibigay ni stock modem, then hindi practical na mag dagdag ng third-party router sa setup mo.
Additionally, sa pagkakaalam ko may major undersea data cable na nasira sometime early this year and maraming affected na lugar at kasama Philippines dun. Might be the cause of some connection hiccups. I'm not sure kung naayos na yun though.
Posting this for insight. Hope it helps.
