Whether you purchase fingerless, full finger, insulated, gel, or winter cycling gloves, you want to get the right pair for the job. For instance, if you are suffering from hand numbness while riding (cyclists palsy), a cycling glove with gel padding in the palm as well as a channel for the ulnar nerve may provide relief.
Cycling gloves are designed by sewing various panels together, and presumably the more panels the more contoured the glove is and the better it fits. Cycling gloves with more panels, densities, and fabrics mated into one glove are going to cost more, but this may be well worth the investment.
