Short answer: the JBL Partybox 310 for the deepest, most balanced sound in the class. It has the deepest bass of any battery powered speaker and the most balanced sound in the class, and its handle and wheels make transport easy, but it is very large. The Partybox 100 is the smaller, lighter, quite neutral alternative with pretty deep bass and only a slight upper-mid peak.
Buy the JBL Partybox 310 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Partybox 330, which replaces the JBL Partybox 310.
Battery life favors the JBL Partybox 310: rated for 18 hours against 12 hours for the JBL Partybox 100.
If water resistance matters to you, the JBL Partybox 310 at IPX4 (splashing) holds up far better than the JBL Partybox 100 at no water resistance.
