Which iPhone repair center would be considered as the best alternative to AppleCare in Singapore?

I have found this named Digital Hospital located both at Bugis Junction and Sim Lim Square. Are they trusted? This is the suggested url I found: https://digitalhospital.com.sg/iphone-screen-repair/ Which iPhone repair center would be considered as the best alternative to AppleCare in Singapore

Nnaybe you should go to ifixit

Their web page seems okay but how long will they
take to repair? Leave your phone and come back after
one month? No way
Inside Bugis Junction market there's a on the spot
repair shop, they repair phones right in front of you

If you bring your phone to a repair center other than AppleCare, you are running a risk as they are not the authorized repair dealer for Apple. So why not do some part time work and save some money and bring your iphone to Applecare which is much safer?
sim lim square shops, some of whom are known to be shady.
