FX553 here
Positive:
If you are talking about performance, this laptop has an excellent price to performance ratio(poly roadshow pricing was $1174). Playing a light game like League of Ledgends, it can reliably get 120fps. I have also tried slightly heavier but older titles such as Dying light and GTA 5, both on high settings, and I get playable fps(never actually measured it).
I play games with an external 1080p monitor and a rgb mechanical keyboard.
The keyboard on it feels nice to type/game on as it has a nice tactile sort of bump when u hit the bottom(compared to other laptop keyboards with those mushy 'mashed potato' keys). However, if you own a mechanical keyboard, it still won't compare to that.
Negative:
The display. It has bad viewing angles, my eyes need to be pretty much parallel to the screen to see things without loss of colour. And even then, colours still look bad when I plug in my 4+ year old midrange monitor and put them side by side and compare them(the FX553 has a white hue over the whole screen).

but given the fact that operation of the laptop requires you to sit still, it really does not affect day to day usage that much.
Fingerprint magnet. The top of the laptop and the area under the keyboard where your palms would rest are both fingerprint magnets as they are both made of matte-ish black plastic. Sweaty palms beware
That all from me, hope you found it useful
