There are several reasons you should seal your pavers. The most dramatic is for the aesthetic results. Acrylic sealers intensify the subtle colors and provide a glossy sheen to even the most haggard of paved surfaces. So, if you have an intricate design, or really want the pavers to be a noticeable part of your landscape, go for it!
Some of the functional reasons for sealing your pavers are: protection from stain penetration (usually dripping oil or the occasional spilled pina colada), it helps prevent insect intrusion (ants, mostly), helps resist mildew, inhibits weed growth, helps prevent tire marking, helps to prevent efflorescence (common in concrete pavers in some areas), and for ease of maintenance.
A solvent-based sealer provides much deeper penetration than the water-based product. Acrylic, when dissolved into a solvent, it is able to penetrate much farther than when suspended in water. This deeper solvent penetration and higher acrylic solid content provides much longer protection from surface wear.
