Sounds like you need to do some real research and understand things so YOU can select the right turbo that YOU want for YOUR application instead of basing your decision off some youtube videos....start with this:

As long as its sized properly and you make sure the oil supply will never run dry, or cook after you turn the car off... I've heard good things about Borg-warner and Garrett. Look at it this way they can't really be made bad or they just won't work, spinning above 150000rpm they would just explode, any oem one should be good, ied avoid ebay ones

Technology wise look for a ball bearing one that takes a external wastegate and has a ceramic turbine. They will require more to rebuild should it need it, but there's less friction and better flow
