I'm not so sure about Lenovo but I have had the opportunity to try the new Nitro 5 and I would say that it is great. Good gaming performance, good product build, smooth display when it comes to watching movies or gaming,  overall I think it is worth the buck as compared to many models on the market that provides the same specs.

You can check out these 3 models as they are within your current budget range:

I believe they are also doing cashback plus rebate right now as well as giving out a free bag pack if you purchase through Shopee, so i think it's a good deal. According to their reviews on Shopee, deliveries are usually quick and safe so I don't think you need to worry on that part.

I wouldn’t touch Acer laptop also.
I used to own a laptop from them, day one brought back and rosak, brought back to shop but shopkeeper said need bring back Acer repair Center, causing wait time for nearly a month to get it back.
