Sealed bearings are usually a cartridge bearing, while regular bearings are loose balls or balls in a retainer ring. A sealed unit is probably better for wet weather, but the unsealed ones are fine and usually a better bargain. JIS and ISO are identical except for the crown race diameter. JIS 27.0 mm ISO 26.4 mm JIS was usually used on Japanese brands, and ISO on most everything that's not French or Italian. If you want to use an ISO headset on JIS, the crown race can be milled down to 26.5 by any decently equipped bike shop. Italian bikes can usually take an ISO model. Italian standard headsets are obsolete.
