for me, the answer is no.
and that mon gets to play on the professors farm and not fight in gyms.

That combination is useful against Gengar.

I see three variants of nidoqueen:

(1) Poison attacker with PJ/SW; Only needed against fairies
(2) Ground attacker with B/EQ; Used in these rare cases to attack or prestige against Jolteon
(3) Defender with PJ/EQ, unfortunately low on CP, not really usefull.

It is a niche-PKM, i keep some, but really rarely use them.
