is still worth it to buy apple watch ultra 1 ?

Hello everyone I'm just asking if it is still worth it to buy apple watch ultra 1 because I find used one battery is 88% and gonna cost 420$ on the other side the ultra watch 3 is gonna cost about 850$
I already had apple watches before series 2 , 3 , 7 but have been with for so long so I believe it is time for me to upgrade and I read that they stop releasing update for ultra 1 any recommendation or tips
