Is the Note 9 worth the upgrade????

So far I've seen several post claiming about the trade in policy. Now that Samsung has the double your trade in promotion I was wondering since I have the Note 8 should I even go through the hastle of upgrading??? I wouldn't want Samsung to get over on me let alone. Shell out an extra $250 on a phone I'm supposed to get doe $499????
