ah naruto is really long since it has 200+ episodes in both seasons and the anime has quite a few filler episodes too so it’ll definitely take a while to watch (it took me a few months to get up to date) if you’ve got a lot of free time on your hands or you’re dedicated to just sticking to watching an anime as frequently as possible then give it a chance!!
the manga would take longer to read (600+ chapters) but there’s more plot relevant stuff so you don’t have to worry about fillers and it’s further ahead than the anime
overall, it’ll be a challenge but it’s up to whether you think it’ll be worth it! i hope i helped a little with your decision uvu
