based on how the lore looks Seeker's view males with a higher regard then Keepers do. since male names for Keepers are literally First/Second/Third son of <Mother's Name>, where as the male Nuhn's (breeding males) first name becomes the surname of every female Miqo'te he sires (Males being considered the family starters in Seeker Culture, whereas in Keeper Culture everything is based on the mother). I think Miqo'te due to their gender inequality don't really care for marriage as we view it (monogamous view on marriage), but I'd think Keeper's would be more drawn to it than Seeker's are.

You also have to note is Seeker culture one may be a Nuhn but are rarely ever the leader.

regretfully this is all conjecture based on the naming conventions lore post.

for those who left society to be an adventurer, well each one would probably view it differently. Some may enjoy the idea, some the meaning behind it, other's may view it as a treasure to be gained.
