i grabbed a pair of 990v6s last year when i was spending way more time on my feet doing yard work and weekend hikes, and honestly for *my* situation they've held up really well. that said, the hype around them is partly about the aesthetic and heritage - people want them because they look good and have that classic appeal. if you're genuinely just doing casual walks and light jogging a few times a week, you're probably not going to notice a massive difference between the 990v6 and something like a new balance 520 or even a good pair of asics or saucony shoes in the $80 - 120 range. the price jump is real, and unless you're putting in serious mileage or dealing with specific foot issues, dropping $200+ might feel wasteful.
where the 990v6 actually shines is durability and that snug, supportive feel that keeps your feet happy during longer activities. the materials are nicer and they tend to last longer before the cushioning breaks down. but here's the thing - if you're not hammering them with heavy use, a mid-range shoe will work totally fine and might even feel just as comfortable for your needs. i'd say try on a few options in that cheaper range first and see how they feel. if your feet feel great and you're happy with how they perform, bank that extra cash. save the 990v6s for when you're either really committed to more frequent activity or you want something you know will last through years of regular use without needing replacement.
