Theres quite abit of choice for bikes below 10k in similar classes, hence i wont go into specific comparison. But in general, the NS advantage over most most bikes on the segment(or yours) would be

1. Comparatively cheap, you can get a used NS ABS for 5k or so. A brand new one cost around 9-10k. Given that its a rather straight forward bike without complicated systems, tested and proven, id say its a safe bet to get a used one. Especially so that its your first one, save the extra cash for safety upgrades(tyres/crashbars) and other minor useful accessories or even attend a proper safety riding course instead of ones in driving school.

2. Fall safe, as in, its not expensive to drop nor would damage many parts(minor drops). The bike is pretty simple, even without a crashbar, a simple fall might only cost you a handlebar, side mirrors and a signal lamp replacement.

3. Lightweight, not as light if you were to compare to 150ccs, but for the power vs displacement vs weight, the NS sports a pretty decent ratio. Its handles pretty well for a beginner to learn too.

4. Cheap spareparts and widely available, you can source spareparts directly from modenas or from us, service plus, 3rd party shopee reseller etc. I would go as far as to say, being an "odd brand" in malaysia, its unlikely for you to have issue finding for parts, and not to mention they cost pretty damm cheap in comparison to other smaller niche companies(KTNS/ZONTES/NAZA/CFMOTO).
These, are my personal opinion.
