I just bought a M5 Macbook Pro 2 weeks ago. Thinking of returning it and getting a M5 Pro with the same configuration but only $200 more. How should I compare M5 vs M5 Pro?

You'll get slightly more performance and ever so slightly less battery life. I'd do it

Thanks for the advice! Gonna do it.

You might also get more monitor support:

M5 Supports up to two external displays over any combination of Thunderbolt and HDMI ports:

Two displays up to a native resolution of 6K at 60Hz or 4K at 144Hz or

One display up to a native resolution of 8K at 60Hz or 5K at 120Hz or 4K at 240Hz

M5 Pro Supports up to three external displays over any combination of Thunderbolt and HDMI ports:

Three displays up to a native resolution of 6K at 60Hz or 4K at 144Hz or

One display up to a native resolution of 8K at 60Hz or 5K at 120Hz or 4K at 240Hz plus a second display up to a native resolution of 5K at 120Hz or 4K at 200Hz
