Front metal gate repaint | paint brand suggestions

I am planning on getting my front metal gate repainted.
It’s been 4 years since the house was built and the paint (currently diamond synthetic enamel) has lost its life.

I wanted to get Berger NU but no one in the market recommend using Berger NU. Everyone says, stick to diamond or if you want to pay premium, go for ici Dulux.

Keeping the price window, diamond, Brighto and Nippon almost all fall in same bracket. Berger NU is rather cheap and Dulux is expensive. What is your suggestion on which way should I lean to ?

To answer my own question for anyone who is having similar issue:
Diamond paints (High gloss enamel)

  • Overall product line is superior
  • Everlast product line is inferior

Berger paints (High gloss enamel)

  • NU is lowest standard in this category
  • Synthetic enamel is at 2nd position
  • VIP is at 1st position.

So instead of going with Berger NU. Go with Diamond Overall.
but if you are planning to go with Berger Synthetic Enamel or VIP, then by all means go with Berger.
