I can't make up my mind or know anything about! What's the big difference between Humminbird Helix 10 Chrip Mega SI GPS G2N Combo and Humminbird Helix 10 SI GPS G2N Combo? And what does chirp do? Trying to figure out if I want to break the bank or not?

They are the same unit except you left off some of the model designations.
There is only one G2N SI model and that is the MEGA SI.
MEGA means 1.2 MKz (1200 kHz) Imaging.
There is the discontinued Helix 10 SI GPS and it has no CHIRP sonar or CHIRP Imaging like the MEGA units have. That model is on close-out sale by several retailers.
Do a web search for CHIRP Sonar.
