Their shields makes them worthwhile as a skirmisher screen, however, and I use mine to soak up enemy missile fire. This allows for the first wave, not to mention your archers/slingers, to remain at full health during the skirmishing phase.
The higher stat units are peltasts, and they play double duty. After they've used all their javelins, they're tough enough to attack, but try to keep them as a flanking force. They're not THAT durable and will probably get cut to ribbons in a straight fight, but at least they're capable of doing something more than waiting out the timer. Despite this, I usually recruit javelinmen instead of peltasts, just to save a little in upkeep, and use some variety of dedicated flankers.
Ultimately though, yeah, archers are more effective and versatile. While I don't mind factions that rely on javelinmen anymore, there are definitely things you can pull off with archers (or even slingers) that javelin units will struggle with. I'm not so sure the same can be said in reverse. Sorry I can't be more helpful.
