I avoid acrylics like the plague. Dont like em at all.
I did get some direction from a FB group towards some articles that listed the like RLM colors. I got some Humbrol in those and will go with them. They should be close enough.
I use both acrylics and enamels all the time. Tamiya are acrylics and are great for airbrushing. Some folks say they are awful for handbrushing - which I had no issues handbrushing them. Tamiya also carry lacquer paints as well but they are smelly.
But back on track… acrylics are a whole different animal. They require a primer coat for better adherence when using acrylics. No different than having a primer coat for enamels. Humbrol are great paints but they come in small tins - thus you will need to buy more for your paint stash should you use them up. Nothing wrong with Humbrol paints, just not economically viable for me.
As I've mentioned above, I use mostly acrylics and enamels. Some enamels are decades old from my youth years and still good in the bottles. Here's my paints brand list I have in my stash…
Tamiya acrylics - I do have one bottle of their lacquer line; Titanium Silver
Testors Model Master acrylics and enamels
Testors enamels in square bottles
Mission Models acrylics - these paints are highly recommended!
AK Interactive Real Colors - also highly recommended!
Aeromaster acrylics
Pollyscale acrylics
Vallejo - not a huge fan of them but I hardly use them
Akan acrylics - fantastic colors from Linden Hill Company
Revell acrylics -I have one tin of their color. Great paint with good coverage.
Gunze/Mr. Color acrylics - another highly recommended line.
As you can see, most of my paints are acrylics. Enamels are slowly going away (Model Master line are gone in both acrylics and enamels) white the exception of Testors square bottles basic color line.
Keep in mind, not all acrylics are alike. You just need to experiment with the paint to thinner ratio and find what works. I use mostly lacquer thinner to thin most of my paints except a few brands. Some acrylics don't play nice with lacquer thinner. If in doubt, use the paint brand thinner when using acrylics.
