Is acer is the best company for laptop or not?

Most laptop manufactures use parts from the same sources.

Dont worry too much about the brand. Its what is inside which count. You can get Acer

laptops with low spec and high spec. Similarly this is the same with other laptop providers

like Asus and HP and Sony and DELL.

My advice is check the processor and memory and hard drive. if these are good, dont

worry so much about the brand
