I couldn't figure out what currency P10,000 is, so hopefully, this isn't outside your comfort zone, but the Razer Kishi v1 is 40$ on Amazon, great controller, been using mine for hours on end for a year now thus I consider it a good investment.
I like my razer kishi for xbox https://www.microsoft.com/d/razer-kishi-for-android-xbox/92kzg88sz07q?rtc=1
as I prefer the handheld feeling over the heavier controller and clip setup. Given its low sale price I think the kishi xbox edition had been discontinued. There is a V2 out now for android without the Xbox branding.
There are some downsides to the Kishi. It has no headphone jack or usb-c pass through audio which i did not realize when i purchased it. So when i need to play with headphones i have a clip for the 8Bitdo Sn30 Pro+ soI can plug headphones into my phone.
But in all honestly I have been considering getting a clip for my xbox controller. I can't speak about the steel series stratus as I have never used it but between my kishi and sn30 pro+ I prefer the feel/responsiveness of the xbox controller sticks and buttons
However, overall I would probably still go with a handheld controller like the razer kishi, Backbone One or Gamesir x2. It is hard to beat that handheld console feeling they provide. The backbone one I believe does have a 3.5mm audio jack that the other two lack. The razer kishi V1 (non xbox branded version) is on sale right now on amazon https://www.amazon.com/Razer-Kishi-Controller-Android-Passthrough-Thumbsticks/dp/B086X8DHN2/ref=sr_1_2?crid=18SV4UDQ17UF2&keywords=razer%2Bkishi%2Bxbox&qid=1669682668&sprefix=razer%2Bkishi%2Bxbo%2Caps%2C153&sr=8-2&th=1

Android Emulators are most compatible with those controllers. Use DIG as an organizer for all your emulators and some apps are still not optimized on Android 11 to use SD Card access but DIG can be used to bypass this if you plan to store games in SD Card. Otherwise, use emulators as you please without DIG.
You can use DualShock 4 controllers or DualSense controllers as well but sometimes there is a compatibility issues or remapping that has to be done for it to work properly with some Emulators. Up to you.
