Several reasons:
1. Your backup strategy. No character is going to have his main schtick be effective in every combat. In the combats where your main schtick doesn't work as well, you're going to have something else to do. If you're a cleric, that is probably healing and buffing spells like recitation, etc. If you're a wizard, you have other conjurations like acid fog, evard's black tentacles, glitterdust, web, and (at least according to the RAW) the orb spells. You also have access to fireball, haste etc.
A character who summons and heals is very different from a character who summons and blasts.
2. Planar binding. Planar binding admits any kind of negotiation you want including strong-arming weaker outsiders. For a summoner who doesn't object to obtaining his minions under the threat of destruction, that's a lot cheaper than planar ally spells which always require recompense/sacrifice.
3. Because the character you want to play is not devout.
4. Prestige classes like the initiate of the sevenfold veil and fatespinner.
