I think China version most probably won't have widewine L1 but will support more games with higher fps option enabled.

Malaysia version have widewine L1 but some games like honour of kings don't have option to enable high fps like China rom.

Neo3 price is not dropping. How much do you get it for now? I got it with Lazada bonus and credit card voucher for RM1,6xx. Unless you can get it cheaper now, better wait for 1-2 more months since more phones are going to launch soon. Mi13 is also coming. Neo 5 is also coming soon.

If you ask me, I would strongly recommend you to reconsider your decision to purchase Neo3. Although I quite like it, but I would think twice about it if Im going to use it for say 5 years in your case.

1. SoC - I would have more faith in Qualcomm updating their drivers in Play Store than Mediatek (Neo3 being powered by Mediatek Dimensity 8100)
2. Screen - Yes, it is also OLED but one made by Chinese companies. Their peak brightness usually around 700-800 (which is better than LCD) but still behind Samsung which usually goes over 1000 nits. Also Samsung ones suffer less in low brightness mode. Even my S9+ which is almost 5 years old has better readability than Neo 3. Click on the link below to view the comparison. The first picture is auto brightness and you can see Neo3 is much dimmer than S9+. Even after I manually adjusted the brightness to match S9+, you can still see the S9+ is still slightly better, but very close.

So far, Realme has updated their phone quite regularly and Im pretty pleased with that. However the phone has only been a year. My other phone is a Realme 6 and that havent been updated for quite some time. Of course that's a low end phone but Neo3 isn't exactly a high end model either.
