Ah, but Ice Storm is nice in that it bypasses SR, has two damage types, which almost always guarantees some effects, and can halt visibility and movement as a mage escape spell.
It's all about how you use it, but I've used Ice Storm to much better effect than Fireball. Plus what other evocation spells are at 4th level that do reasonable area damage?
Ice storm is an evocation that does not bypass SR, it's cold damage is 2d6 and unlikely to significantly power past cold resistance, it only slows (does not halt) movement in a 20 ft. radius area, does not explicitly provide concealment/block visibility and its blocking only lasts 1 round. Compare that versus any of the wall spells. It's 3d6 bludgeoning is from magical hailstones, so is that subject to DR and count as magical bludgeoning but potentially subject to more reductions of the 5d6 damage?
Ooh, its long range.
And it cannot be evasion dodged by monks and rogues as it has no reflex save agains its 5d6 damage.
Ice Storm
Evocation [Cold]
Level: Drd 4, Sor/Wiz 4, Water 5
Components: V, S, M/DF
Casting Time: 1 standard action
Range: Long (400 ft. + 40 ft./level)
Area: Cylinder (20-ft. radius, 40 ft. high)
Duration: 1 full round
Saving Throw: None
Spell Resistance: Yes
Great magical hailstones pound down for 1 full round, dealing 3d6 points of bludgeoning damage and 2d6 points of cold damage to every creature in the area. A -4 penalty applies to each Listen check made within the ice storm’s effect, and all land movement within its area is at half speed. At the end of the duration, the hail disappears, leaving no aftereffects (other than the damage dealt).
Arcane Material Component
A pinch of dust and a few drops of water.
I'd rather do wall of fire or ice
Wall of Fire
Evocation [Fire]
Level: Drd 5, Fire 4, Sor/Wiz 4
Components: V, S, M/DF
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Effect: Opaque sheet of flame up to 20 ft. long/level or a ring of fire with a radius of up to 5 ft. per two levels; either form 20 ft. high
Duration: Concentration + 1 round/level
Saving Throw: None
Spell Resistance: Yes
An immobile, blazing curtain of shimmering violet fire springs into existence. One side of the wall, selected by you, sends forth waves of heat, dealing 2d4 points of fire damage to creatures within 10 feet and 1d4 points of fire damage to those past 10 feet but within 20 feet. The wall deals this damage when it appears and on your turn each round to all creatures in the area. In addition, the wall deals 2d6 points of fire damage +1 point of fire damage per caster level (maximum +20) to any creature passing through it. The wall deals double damage to undead creatures.
If you evoke the wall so that it appears where creatures are, each creature takes damage as if passing through the wall. If any 5-foot length of wall takes 20 points of cold damage or more in 1 round, that length goes out. (Do not divide cold damage by 4, as normal for objects.)
Wall of fire can be made permanent with a permanency spell. A permanent wall of fire that is extinguished by cold damage becomes inactive for 10 minutes, then reforms at normal strength.

Wall of Ice
Evocation [Cold]
Level: Sor/Wiz 4
Components: V, S, M
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Effect: Anchored plane of ice, up to one 10-ft. square/level, or hemisphere of ice with a radius of up to 3 ft. + 1 ft./level
Duration: 1 min./level
Saving Throw: Reflex negates; see text
Spell Resistance: Yes
This spell creates an anchored plane of ice or a hemisphere of ice, depending on the version selected. A wall of ice cannot form in an area occupied by physical objects or creatures. Its surface must be smooth and unbroken when created. Any creature adjacent to the wall when it is created may attempt a Reflex save to disrupt the wall as it is being formed. A successful save indicates that the spell automatically fails. Fire can melt a wall of ice, and it deals full damage to the wall (instead of the normal half damage taken by objects). Suddenly melting a wall of ice creates a great cloud of steamy fog that lasts for 10 minutes.
Ice Plane
A sheet of strong, hard ice appears. The wall is 1 inch thick per caster level. It covers up to a 10-foot-square area per caster level (so a 10th-level wizard can create a wall of ice 100 feet long and 10 feet high, a wall 50 feet long and 20 feet high, or some other combination of length and height that does not exceed 1,000 square feet). The plane can be oriented in any fashion as long as it is anchored. A vertical wall need only be anchored on the floor, while a horizontal or slanting wall must be anchored on two opposite sides.
Each 10-foot square of wall has 3 hit points per inch of thickness. Creatures can hit the wall automatically. A section of wall whose hit points drop to 0 is breached. If a creature tries to break through the wall with a single attack, the DC for the Strength check is 15 + caster level.
Even when the ice has been broken through, a sheet of frigid air remains. Any creature stepping through it (including the one who broke through the wall) takes 1d6 points of cold damage +1 point per caster level (no save).
Hemisphere
The wall takes the form of a hemisphere whose maximum radius is 3 feet + 1 foot per caster level. The hemisphere is as hard to break through as the ice plane form, but it does not deal damage to those who go through a breach.
Material Component
A small piece of quartz or similar rock crystal.
