Just to add to comments on CPU. Base frequency (2.9 and 2.6 GHz) is not a good measure of performance, rather that lower base frequency may translate to using less power and so better battery life. You also need to look at peak Turbo boost (3.9 and 4.3 GHz). So number 2 is better because a) newer generation of processor, b) faster peak GHz, c) 6 cores and possibly d) lower base frequency leading to better battery life.Number 1 has: Core i7-7820HQ for CPU
Number 2 has: Core i7-8850H for CPU

Edits:
Number 2 has slightly large Cache - another marginal improvement.
But I would not choose based just on CPU. There are other important factors that others have touched on.
Graphics: Both models had a choice of Intel (on chip) graphics or a discrete AMD graphics card. That might affect your game play. That is one area where option 1 might be better if it has AMD graphics and option 2 does not.
macOS: Both support the latest macOS 13 (Ventura), but it is likely(?) that option 1 will not be supported for macOS 14. This is probably not an issue for you, except that Macs not supported by latest macOS will only get security fixes for a further 2 years.
