Some fruits imo get (hard) carried by their users. Give the azure dragon for example to Kid or DR base Luffy and you are getting a little stronger and more durable hybrid P1.
Top tiers shredding through that durabiliy and low top tiers+ are clowning the dragon form.
Flame dragon torch is op, but not to the extent, where you can call it the best or strongest fruit imo.
Similar thing with the Soru no mi. Big Mom is a natural born destroyer. Looked at it rationally you are getting (extremely) watered down logia base attacks for your arsenal and that's mostly it.
Kizaru for example is pretty much made out of the element, that's the peak of the Soru no mi's elemental ability, while he additionally has access to op, mid top tier filtering light speed and we have not even seen its awakening yet.
Imo there are clearly levels to it.
If not for FS the warp no mi might have even been in the top3.
Right now I'd still go with the Pika no mi. All out Nika, Imu's and Loki's fruits are going to be amped by extremely powerful side perks, while Kizaru is jist chilling with barrier CoA and FS, if he's lucky and still giving out aura, where post Kaido Luffy loses his shit.
So even if those fruits will go super hard later on, the Pika no mi might ultimately still prevail.
