Looking for everyday blue ink.

Hi! Very new to this hobby, and looking for an ink to use everyday for notes. Preferably blue. I'm in India, and not all inks are available here.

Till now, I have shortlisted these:

Pilot Blue

Waterman Florida Blue

Waterman Mysterious Blue

Pelikan 4001 Royal Blue

Sheaffer Skrip Blue

Diamine Majestic Blue (Really want this but it's twice the price of the others)

I cannot afford anything more expensive than these. I am open to more options, as long as I can find them here. Please help me choose, thank you. I'll be using the ink with Lamy Safari F and Kaweco Perkeo F on Camlin Primeo 68 gsm paper.
