For better gaming performance, can go for the 4755g and A43sv.
For better warranty support, can go for those with 3 years warranty, though my vote goes  to the L745 

Personally I would go for Toshiba because I know Teledynamics technicians will always be there for me 
Whether the laptop runs smooth or not depends on how you manage your stuffs inside?
What kind of software problems o?

I'm not so sure about the 4755g (there were a few comments on freezing) and z470 (the pink looks awkward haha)... din't really come across a lot of reviews

Based on my experiences, its not bad la haha
Yup, there a Teledynamics service center on the top floor of LYP, another one at Shah Alam

You could always delete them bloatwares

If you're more interested in on-site warranty support, then can consider Dell as well~

Older model? That one is L755 (15" laptop). The one in the 2nd link is the correct one
