vue引入組件方式，哪個(gè)好一點(diǎn)？

1、直接路徑引入
components: {

    'xyAddNew': () => import('../../components/sym_1/item_a/addNew'),
    'xyEdit': () => import('../../components/sym_1/item_a/edit')     

}

2、這個(gè)是封裝為組建的方式？
import {

xyHeader,
xySide

} from '@/components';
export default {

name: 'index',
components: {
    xyHeader,
    xySide
}

}
