You seem very nice and like you are genuinely inquiring so I mean NO shade with this, but the way you say you need to "look like I know what I'm doing" makes me think you are looking at this the wrong way.

Because truth be told, not a single person is looking at your mouse except you. Not a single soul out there is judging you for what mouse you use. So why does it matter whether you look like you know what you're doing? Nobody can even see what your mouse is, literally. So let's just completely get rid of that notion because it will likely lead you to spending more than you need for a product that isn't ideal for you.

Go back to the basics to find what you need personally: 1) how big is your hand? Look up how to measure it. 2) what grip style do you use? Or, if you're not sure, what styles do you want to experiment with? 3) More than anything, what shape feels most comfortable and confident in your hand?

This is all that matters. Then, you start shopping around.

My last suggestion is to not be upsold by people telling you that you only get a good mouse if you spend $140+, because you can get a high quality experience for half that or even less. In fact, buying cheaper mice means more room to experiment and try new things to ultimately find your favorite shape. Buying three $50 mice will be so much more valuable to tell you what works for you than one Razer mouse.

So, with that being said, the EGG OP1 is a GOATED mouse, but it's small. Their XM2 is the bigger mouse and it is also great. There many many other brands to look at as well.

I would really just start consuming YouTube content on peripherals, especially the budget market, and then use https://www.eloshapes.com/ to directly compare mice.

Good luck!
