A: Start at issue 1 (There's technically a miniseries that's before this but it doesn't even matter) and read everything. This is how you get the most out of the comics, but it also means you encounter the worst the comic has to offer. Conversely, you get to appreciate the absolute best it has to offer too
B: Start at issue 160. This is when the writer that's generally considered to be "the good one" (Ian Flynn) starts writing for the comic and begins cleaning up the mess other writers left behind. You get the best the comic has to offer, but you also miss out on a lot of context, context that makes his best stories as good as they are. Also you will likely need to read the wiki to clarify certain things
C: Start at the reboot at Sonic 252. The absolute safest option. This is the start of the reboot continuity which is much closer to the games and is more consistent in quality. However the bulk of it is an adaptation of Unleashed and it's interrupted by a shitty crossover that means nothing. You never quite hit the highs of the pre-reboot, but never hit the lows either. Has more resolution than the pre-reboot though, but in general, don't expect resolution on some things.
And if you need a reading guide, here's the best one I've found
