is geekbench score a good measure ? for laptops

Basically everything comes to your Personal choice along with the type of work / requirements from the Laptop that you need

Answering to your Title Question       

For starters Geekbench is a processor benchmarking program that  measures scores of the system's performance  by executing a series of tests on a processor as well as times how long the processor takes to complete the tasks & these are comparable across platforms. The quicker the CPU completes the tests, the higher the GeekBench score

When comparing laptops, a common benchmark is the CPU benchmark (Central Processing Unit) performance, which can be measured by its clock speed, number of cores, and the architecture. Another common benchmark is the GPU benchmark (Graphics Processing Unit) performance, which is usually tested using benchmarking tools like 3DMark and GFXBench. Other benchmarks to consider include PCMark, which measures the overall system performance, and Geekbench, which tests the CPU and memory performance

It's important to note that any benchmark scores should only be used as a general reference and not the sole factor in determining the overall performance of a laptop 

Factors such as the configuration of the system, memory, storage, and graphics card, among others, can also significantly impact the performance

It's also worth mentioning that benchmarks are often performed under specific conditions, and the results may vary in real-world usage. For example, a scenario where in a laptop with high benchmark scores may perform poorly in demanding tasks like video editing or gaming due to other limiting factors such as thermal throttling or inadequate cooling.

In conclusion, benchmark scores can be a useful tool in comparing laptops, but it's essential to consider other factors to get a more comprehensive picture of the device's performance. Benchmarks & specs do matter to get good value of your money , However once again, keep in mind, it is always a good mix of things i.e. Focusing purely on benchmarks is also bad because in Laptops things like keyboard, display, upgradability, portability, engineering involved, materials also drive it up

The best Laptop benchmark is your satisfaction level. If the machine is doing what it's supposed to do, and you're happy with that, that is the best benchmark that you can have
