Hmm...

Bowls would give multiple options. Small ones would be stealthy and good for smoking at home with no one noticing. Bigger ones wouldn't be as stealthy but wouldn't hit as harsh. Overall, bowls are only preferable for smoking by myself at home without getting caught.

Bongs get me ripped, but I couldn't stand to hit bongs constantly...

Blunts are better than joints in my opinion, they're easily portable, popular with groups, and they hit really smooth... only downside is no sneak-smoking.

Personally, I'd have to go with Blunts, although a nice big glass bowl comes in a close second.
