Unfortunately since these fora belong to PC Specialist (PCS) who sell custom built gaming laptops and PCs we can't advise on other builds or brands, sorry.
If you post a budget and details about what you'll be using for (any specific games?) people can suggest options.
You can then weigh up the performance and hardware you get with a PCS spec VS Acer or any other models you're looking at for the price, and come to a decision on what's best value
