thanks for sharing!haven't used the 13R but have used plenty of phones with SD8 Gen 3 and have used my fair share of OnePlus phones. if it were me, out of those 3, i'll pick 13R without a doubt, especially for like my parents who usually their phones for a long time.
1. Chipset. having a good chipset will help the phone remain nice to use for a longer period of time and SD8 Gen 3 is the best out of the 3 by far. Good optimisations can help, but having extra head room in terms of raw performance helps even more. like just in case apps become more demanding in the future, or when the phone gets filled with more data after a while.
2. Good track record with software. My mom's been using OnePlus 10R and it had been getting fairly regular updates over the years. Currently on the June 2025 security patch. Plus they performance didn't noticeably deteriorate when these updates, both small and large. Still feels as smooth and responsive now. Whereas my dad's Poco X4 GT with the same exact chipset as the 10R actually runs like crap on the latest HyperOS. laggy, slow, seems like with updates they introduced/turned on some of the ads settings that I've turned off before, etc. It runs like a phone that is like 2 years older than the OnePlus 10R even though they came out around the same time. But that said, this could just be a xiaomi thing. Can't comment on Honor or Reno though since not much experience with them.
BUT, if you care more about camera, my bet is that Reno 14 will fare better than the other 2 (only one with an actual telephoto camera too). While they all under same parent company, they usually try to maintain a seperation between OPPO and OnePlus by making sure OPPO phones of the same price/category will have better imagine processing than OnePlus. lol. But for a mid range phone I'm not sure if the difference will actually be that huge or not though. Pretty sure 13R won't be potato cam at least.![]()
I decided to get em the Reno 14. selling off the hairdryers to offset the costs.
