please help me about pros and cons, stability, warranty (international) / good customer service, ...

Assuming you are looking for a sole gaming machine.
If solely between this two, I would pick the Illegear, though with RM5k you are only getting the lowest specs and FreeDOS. But no worries, since you can always upgrade later when you have the budget.

As you are aware, the i7 is really a lot more powerful than the quad core AMD A10. I am not really sure the bottlenecking on the AMD will be that obvious during real-life gameplay.. but personally I trust Nvidia's driver updates more, that alone is enough for me to decide. They are more consistent and stable, meaning that you will get graphic boosts in new, popular games every one in a while

Still, the finaly decision lies with you. The MSI comes with 2 years warranty support as well, which is a plus

15.6"
If you don't mind lower specs, can consider this:
GE60-2OE, i7-4700MQ + Nvidia GTX765M + (1920x1080; anti-glare)@RM4299,8GB, 750GB(7200rpm), W8, backlit keyboard

or this:
Illegear RE-15, i7-4700MQ + Nvidia GTX765M + (1920x1080)@RM3799[2.6kg][Onkyo, SoundBlaster Cinema], 8GB, 500GB 7200RPM, FreeDOS, [CPU Options: i7-4700MQ - i7-4900MQ]

You will have more remaining budget for serious upgrades, especially for an SSD, which will significantly boost performance. And of course, don't forget about warranty extension, its important for a notebook this expensive.

ILLEGEAR is better bacause you can add a SSD right on the online shop. But for me I think it really depends on ur area. In East Malaysia? maybe ILLEGEAR is not a good choice. In West Malaysia? ILLEGEAR is the one to GEAR UP UR GAMING LIFE!

Quality of Illegear has been pretty good so far, not much complaints. But that might be because there are still not that much users yet.
Warranty support (Malaysia and Singapore) is superb. Very fast, although you will have to rely on postage if you are in east Malaysia.
My advice is, no matter what brand you are going for, if you are getting a gaming machine, go for warranty extension.
Gaming machines will be put to stress during your gaming sessions, and heat will kill the notebook, and its not cheap to replace high-end hardwares inside the machine 

3 years is always the best since the rate of spoilage is higher between year 2-3 when compared to 1-2.
But do take note that will exceed your budget already if you decide to get the RS-15 Lite.
Try and bargain with PrinceJ or any other Illegear resellers before you purchase ya, I'm sure they will be able to help give some discounts 

Its a relatively older model, but should still be available
