Exeggutor
I have just hatched an Exeggcute with 89% IV. I already have 1 Exeggutor with 87% IV, 1640 CP and Confusion/Solar Beam. I have 22 candies and Exeggcute are really rare near me---I have only ever caught 1 in the wild. Should I power up my current Exeggutor or wait to evolve the new Exeggcute?

I think you mis-understand the rating system. A grade B moveset might still be very good (in some cases a Grade C moveset might be far better than a Grade A moveset for another Pokémon).
None of the Grade B movesets for Exeggutor could ever be described as not useful or 'not good'.
If you're not answering from personal experience it might be more helpful to either post a link to the source of a view or refrain from commenting.
You can power it up,
Indeed. He can, as long as he has enough candy and dust.
not weak to Seakings
Did i miss anything? Is seaking a relevant attacker or defender?
for people who don't have pinsirs,
I eat exeggutors with arcanine or with venomoth. There are more relevant attackers with big type advantage.
and it has a good moveset.
Yes, for defense, it is good. For attacking, i prefer ZH as quick attack.
The worst moveset is ZH/SB,
This is the best attacking moveset.
[Edit: As long as "SB" means Solar Beam and not Seed Bomb; Thanks for comment! /Edit]
followed by ZH/Psychic.
...the second best attacking moveset.
Exeggutor is either useful on attacking or defending if it doesn't have those movesets.
It is easy:
Zen Headbutt: attacker
Confusion: defender.
ZH is an attacking move, as many have said. Confusion is decent as well, but I would prioritize ZH.
With ZH, all charge moves are great because you will likely use Exeggutor as an attacker to take down Vaporeons (of which every gym seems to have at least 2-3). Against Vaporeon, Solar Beam is fantastic and both Psychic and Seed Bomb are very good.
For you, if you have other grass alternatives to take down Vaporeons, I would wait. If not, you can always power up your current one and I'm sure it will do just fine.
You should make a trip to Boston... I spent 1 hour in the park in the middle of the city and literally caught 25 Exeggutes (it is a crazy nest). Goes to show that the game is really imbalanced based on where you live.
